I did test several simple date format convertion, like the one bellow and similar other:
var toParse:String = "Thu Aug 29 2013";
var milliseconds:Number = Date.parse(toParse);
I'd like to know if there exist something as simple as this method to convert the format 29/08/2013 to milliseconds.
Thanks and cheers.
It works the same with 29/08/2013 although the Date.parse just takes it as mm/dd/yyyy. So you need to do:
var toParse:String = "08/29/2013";
var milliseconds:Number = Date.parse(toParse);

I'm trying to get from a time formatted Cell (hh:mm:ss) the hour value, the values can be bigger 24:00:00 for example 20000:00:00 should give 20000:
Table:
if your read the Value of E1:
var total = sheet.getRange("E1").getValue();
Logger.log(total);
The result is:
Sat Apr 12 07:09:21 GMT+00:09 1902
Now I've tried to convert it to a Date object and get the Unix time stamp of it:
var date = new Date(total);
var milsec = date.getTime();
Logger.log(Utilities.formatString("%11.6f",milsec));
var hours = milsec / 1000 / 60 / 60;
Logger.log(hours)
1374127872020.000000
381702.1866722222
The question is how to get the correct value of 20000 ?
Expanding on what Serge did, I wrote some functions that should be a bit easier to read and take into account timezone differences between the spreadsheet and the script.
function getValueAsSeconds(range) {
var value = range.getValue();
// Get the date value in the spreadsheet's timezone.
var spreadsheetTimezone = range.getSheet().getParent().getSpreadsheetTimeZone();
var dateString = Utilities.formatDate(value, spreadsheetTimezone,
'EEE, d MMM yyyy HH:mm:ss');
var date = new Date(dateString);
// Initialize the date of the epoch.
var epoch = new Date('Dec 30, 1899 00:00:00');
// Calculate the number of milliseconds between the epoch and the value.
var diff = date.getTime() - epoch.getTime();
// Convert the milliseconds to seconds and return.
return Math.round(diff / 1000);
}
function getValueAsMinutes(range) {
return getValueAsSeconds(range) / 60;
}
function getValueAsHours(range) {
return getValueAsMinutes(range) / 60;
}
You can use these functions like so:
var range = SpreadsheetApp.getActiveSheet().getRange('A1');
Logger.log(getValueAsHours(range));
Needless to say, this is a lot of work to get the number of hours from a range. Please star Issue 402 which is a feature request to have the ability to get the literal string value from a cell.
There are two new functions getDisplayValue() and getDisplayValues() that returns the datetime or anything exactly the way it looks to you on a Spreadsheet. Check out the documentation here
The value you see (Sat Apr 12 07:09:21 GMT+00:09 1902) is the equivalent date in Javascript standard time that is 20000 hours later than ref date.
you should simply remove the spreadsheet reference value from your result to get what you want.
This code does the trick :
function getHours(){
var sh = SpreadsheetApp.getActiveSpreadsheet();
var cellValue = sh.getRange('E1').getValue();
var eqDate = new Date(cellValue);// this is the date object corresponding to your cell value in JS standard
Logger.log('Cell Date in JS format '+eqDate)
Logger.log('ref date in JS '+new Date(0,0,0,0,0,0));
var testOnZero = eqDate.getTime();Logger.log('Use this with a cell value = 0 to check the value to use in the next line of code '+testOnZero);
var hours = (eqDate.getTime()+ 2.2091616E12 )/3600000 ; // getTime retrieves the value in milliseconds, 2.2091616E12 is the difference between javascript ref and spreadsheet ref.
Logger.log('Value in hours with offset correction : '+hours); // show result in hours (obtained by dividing by 3600000)
}
note : this code gets only hours , if your going to have minutes and/or seconds then it should be developped to handle that too... let us know if you need it.
EDIT : a word of explanation...
Spreadsheets use a reference date of 12/30/1899 while Javascript is using 01/01/1970, that means there is a difference of 25568 days between both references. All this assuming we use the same time zone in both systems. When we convert a date value in a spreadsheet to a javascript date object the GAS engine automatically adds the difference to keep consistency between dates.
In this case we don't want to know the real date of something but rather an absolute hours value, ie a "duration", so we need to remove the 25568 day offset. This is done using the getTime() method that returns milliseconds counted from the JS reference date, the only thing we have to know is the value in milliseconds of the spreadsheet reference date and substract this value from the actual date object. Then a bit of maths to get hours instead of milliseconds and we're done.
I know this seems a bit complicated and I'm not sure my attempt to explain will really clarify the question but it's always worth trying isn't it ?
Anyway the result is what we needed as long as (as stated in the comments) one adjust the offset value according to the time zone settings of the spreadsheet. It would of course be possible to let the script handle that automatically but it would have make the script more complex, not sure it's really necessary.
For simple spreadsheets you may be able to change your spreadsheet timezone to GMT without daylight saving and use this short conversion function:
function durationToSeconds(value) {
var timezoneName = SpreadsheetApp.getActive().getSpreadsheetTimeZone();
if (timezoneName != "Etc/GMT") {
throw new Error("Timezone must be GMT to handle time durations, found " + timezoneName);
}
return (Number(value) + 2209161600000) / 1000;
}
Eric Koleda's answer is in many ways more general. I wrote this while trying to understand how it handles the corner cases with the spreadsheet timezone, browser timezone and the timezone changes in 1900 in Alaska and Stockholm.
Make a cell somewhere with a duration value of "00:00:00". This cell will be used as a reference. Could be a hidden cell, or a cell in a different sheet with config values. E.g. as below:
then write a function with two parameters - 1) value you want to process, and 2) reference value of "00:00:00". E.g.:
function gethours(val, ref) {
let dv = new Date(val)
let dr = new Date(ref)
return (dv.getTime() - dr.getTime())/(1000*60*60)
}
Since whatever Sheets are doing with the Duration type is exactly the same for both, we can now convert them to Dates and subtract, which gives correct value. In the code example above I used .getTime() which gives number of milliseconds since Jan 1, 1970, ... .
If we tried to compute what is exactly happening to the value, and make corrections, code gets too complicated.
One caveat: if the number of hours is very large say 200,000:00:00 there is substantial fractional value showing up since days/years are not exactly 24hrs/365days (? speculating here). Specifically, 200000:00:00 gives 200,000.16 as a result.
I want to compare the date that was created in the spreadsheet with a specific date.
var ss = SpreadsheetApp.getActiveSpreadsheet();
var spreaddate = ss.getSheetByName("sheet123").getRange("B2").getValue();
//--> Thu Dec 12 00:00:00 GMT+09:00 2019
var comparedate = new date(yyyy-mm-dd)//somting like this
if(spreaddate > comparedate){
do something
}
The spreaddate is not recognized as a date.
Even if I try to convert it to a date, it's hard because it's written in letters, not numbers like Thu Dec.
What should I do?
I think the problem is that you're not correctly defining your comparedate. You need to use a capital 'D' new Date().
I'm about to use google sheet as my database for my android app small project. I'm using Google Script to handle the request from my app.
In my google sheet, I store;
A2:A = date as dd/mm/yyyy e.g 21/12/2019 but
the display format is dd-MMM e.g 21-Dec
C2:D = time as hh:mm:ss e.g 21:00:00 but
the display format is hh:mm e.g 21:00
Yes, I need a different format for the display and input.
My google sheet:
When I use google script to get a value of the cell, it seems that it is reformatted
the date looks like this: Sat Jan 01 2019 00:00:00 GMT+0700 (ICT)
the time the other hand, change in value a bit. 20:00:00 to 19:52:48
Is there any function to get cell real values as text without being reformatted?
The only thing that I can think of is instead of using getValues(), I can use getDisplayValues(). The values will not be reformatted, but it is not a solution for me, as it will take the display format.
Snippet of my code:
function updateData(e, sheet) {
var tgl = e.parameter.tgl;
var dtg = e.parameter.dtg;
var plg = e.parameter.plg;
var lbr = e.parameter.lbr;
var rangeHead = sheet.getRange("A2:A");
var valuesHead = rangeHead.getValues();
var rangeFirst = sheet.getRange("C2:D")
var valuesFirst = rangeFirst.getValues();
var rangeSecond = sheet.getRange("G2:G")
var valuesSecond = rangeSecond.getValues();
for (var i = 0; i < valuesHead.length; i++) {
if (valuesHead[i][0] === tgl) {
if(dtg!="null") { valuesFirst[i][0] = dtg; }
if(plg!="null") { valuesFirst[i][1] = plg; }
if(lbr!="null") { valuesSecond[i][0] = lbr; }
break;
}
}
rangeFirst.setValues(valuesFirst);
rangeSecond.setValues(valuesSecond);
}
The code won't work as I will comparing 21/12/2019 with Sat Jan 01 2019 00:00:00 GMT+0700 (GMT).
[UPDATE 1]:
Thank you P-Burke for the enlightenment. Now, I have an idea to solve the date problem. I know that the script pulls the date as date object, but I am unaware that it also saves as a date object. (hehe my bad) I don't realize it as there is no autocomplete when I call values[0][0]. of course, as it recognizes the object type at the run time.
So, my workaround will be; I will call getDate, getMonth+1, and getYear. After that, I will compare with my parameter freely.
Though, the time cell still a bit confusing for me. the time offset is 18 minutes 12 seconds. I don't think it's because of timezone different and my computer clock. the timezone different is too big and I 've made sure that the script, spreadsheet, and local timezone all the same. My computer clock is also only a minute less behind.
[UPDATE 2]:
Alright, enough with the confusion. It seemed that the script converts the time to Date object respect to my local timezone. I got this answer from another thread. So, actually, my local timezone changes many times and some of them have offset smaller than hours unit (one of the timezones used in my area is UTC +7:07:12h). The only source documenting those changes I could find is from https://www.timeanddate.com/time/zone/indonesia/jakarta. Finally, I gave up. For my goodness sake, I will just use getDisplayValue and ignore the seconds. Unless you guys have any other workaround, I will be so grateful.
Thank you once again to the community.
Firstly, and I don't know if this is related to your issue, but the spreadsheet and the script each have their own timezone setting:
Spreadsheet: File >> Spreadsheet Settings >> Time Zone.
Script: File >> Project Properties >> Time Zone.
And if these are different that can lead to confusion. One answer, if all your users are in the same timezone, is to set them to the same. Alternatively these can be determined from within your script as described here, and logic included to handle any differences. I don't understand the few minutes time difference, perhaps your PC clock is inaccurate?
The other point, which I think is more relevant to your question is that you effectively have multiple date/time formats in play. The picture below shows that in the spreadsheet times are edited in one format (02/01/2019 09:00:00), but displayed in whatever format is defined for the cell using the format menu. Yet when the cell values are pulled into a script using getValues() and displayed they appear as follows: Values: [[Thu Jan 31 09:00:00 GMT+00:00 2019, Wed Jan 02 09:00:00 GMT+00:00 2019]].
Yet in the code below, values[0][0] and values[0][1] are actually JavaScript Date() objects and can be compared in the usual way, alternatively they can be reformatted into whatever string format you require as illustrated in the code below:
function myFunction() {
var ss = SpreadsheetApp.getActive();
var ws = ss.getActiveSheet();
var input_range = ws.getRange("A1:B1");
var values = [];
values = input_range.getValues(); // Returns a multi-dimensional array, hence [0][0] to access.
Logger.log("Values: %s", values);
// As Date() objects the usual methods are available.
Logger.log("Date().getMonth(): %s",values[0][0].getMonth());
Logger.log("Date().getYear(): %s",values[0][1].getYear());
// This formats the date as Greenwich Mean Time in the format
// year-month-dateThour-minute-second.
var formattedDate = Utilities.formatDate(values[0][0], "GMT", "yyyy-MM-dd'T'HH:mm:ss'Z'");
Logger.log(formattedDate);
formattedDate = Utilities.formatDate(values[0][1], "GMT", "yyyy-MM-dd'T'HH:mm:ss'Z'");
Logger.log(formattedDate);
}
Logger.log output:
[19-01-31 11:43:17:635 GMT] Values: [[Thu Jan 31 09:00:00 GMT+00:00 2019, Wed Jan 02 09:00:00 GMT+00:00 2019]]
[19-01-31 11:43:17:636 GMT] Date().getMonth(): 0.0
[19-01-31 11:43:17:637 GMT] Date().getYear(): 2019.0
[19-01-31 11:43:17:638 GMT] 2019-01-31T09:00:00Z

I'm trying to write a script which is supposed to send out an email and create two calender entries when submitting a form. To be honest, this is my first script and I am very happy that the email is send out and the calender entries are working as well. The thing which gives me a headache is to subtract 5 days (actually x days) from a defined date.
First I thought I could simply do something like
var liveday = e.values[2];
var newday = liveday-5;
well, this didn't work :-)
I tried more:
var newtime = new Date(liveday);
var yr = newtime.getYear();
var dt = newtime.getDay();
var mt = newtime.getMonth();
var dtnew = dtnew.setDate(mt, dt-5, yr);
But here I received 1418256000000 whereas liveday = 12/01/2014. Not sure why days were added, rather than subtracted.
I am quite confused here and the answer can't be that hard.
I just want to subtract 5 days from 12/01/2014 to receive 11/27/2014.
Thanks for having a look
the comment sends you to a rather complicated serie of codes... there is a far more simple way to get that, here is the code :
function test() {
Logger.log('today= '+new Date()+' and 5 days ago is '+subDaysFromDate(new Date(),5));
}
function subDaysFromDate(date,d){
// d = number of day ro substract and date = start date
var result = new Date(date.getTime()-d*(24*3600*1000));
return result
}
Logger result :
[13-11-18 23:39:50:364 CET] today= Mon Nov 18 2013 23:39:50 GMT+0100 (CET) and 5 days ago is Wed Nov 13 2013 23:39:50 GMT+0100 (CET)
if you want to get the date in the form dd/mm/yyyy use Utilities.formatDate(date, timeZone, 'dd/MM/yyyy), see doc here
Hi I'm having a problem setting a date in as3
here is the code i'm using
var endDate = new Date(2009,9,10);
trace (endDate);
the trace statement always shows the date as 1 month further on the the date I have added eg
10th Oct 2009 instead of 10th september 2009
Is there a way around this?
The month is 0 index.
var endDate = new Date(2009,9-1,10);
Yeah, dates are zero indexed in AS, so you'll need to subtract one
0 indexed like the other said. Try and take a look at this post for more tips on the date object:
How can you save time by using the built in Date class?
It might be because you are converting strings to numbers.
(Implicit coercion of a value of type String to an unrelated type Number.)
If you just make it:
var day:Number=parseInt("10");
var month:Number=parseInt("9");
var year:Number=parseInt("2009");
var adjMonth =month-1;
var endDate = new Date(year,adjMonth,day);
trace(endDate.toString());
It'll work fine.
