I have a long-term problem. I watch on the web, but I did not find right answer.
When I send data from WebAPI-Angular-Controller to Controller is a problem with formatting date. There are real data:
My TimeZone is UTC + 1
MS SQL:
Column type: DateTime2(3) value: 4.7.2015 20:00:00
The client receives the following formats based on the following criteria:
When I edit on WebApiConfig
config.Formatters.JsonFormatter.SerializerSettings.Converters.Add (new IsoDateTimeConverter DateTimeStyles = {} DateTimeStyles.AdjustToUniversal); The client receives 2015-07-04T03: 00: 00Z and this {{time | date 'HH: mm: ss'}} show wrong time. It is show time + 2 hours -> 22:00:00 -> I tried {{time | date 'HH: mm: ss' 'UTC'}}, bud show this time - 1 hour -> 19:00:00.
When I edit on WebApiConfig
config.Formatters.JsonFormatter.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Utc;, so it is the same as first example.
When I edit on WebApiConfig
config.Formatters.JsonFormatter.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Local, so it is the same as first example excepting client receive data; they look like 2015-07-04T22: 00: 00 + 02: 00
When I edit on WebApiConfig
config.Formatters.JsonFormatter.SerializerSettings.DateTimeZoneHandling = DateTimeZoneHandling.Undefined, client receive data; they look like 2015-07-04T20: 00: 00 -> it is look OK, bud problem is elsewhere.
I need this time (20:00:00) - curent time (f.e. 10:00:00) = 10:00:00 diff time, but angular show 11:00:00, why?
there is source from angularController
var d1 = new Date(bq.Done_Time)
var d2 = new Date()
bq.Time_Left = new Date(bq.Done_Time).getTime() - new Date().getTime()
Is the problem on server side or client side? And how can I resolve it?
Thank you very much for your valuable suggestions

I would like to request the last 30 days of CrewHu Import data from today's date in this query. At the moment it is just set to get everything greater than the 25th September 2022 but I want to change this to be a dynamic value. Has anyone else had this problem / knows of a workaround?
let
Source = Json.Document(Web.Contents("https://api.crewhu.com/api" & "/v1/survey?query={""_updated_at"":{""$gte"":""2022-09-25T00:00:00.000Z""}}", [Headers=[X_CREWHU_APITOKEN="xxxxxxxxxxx"]])),
I've tried:
OneMonthAgo = Text.Replace(Text.Start (Text.From(Date.AddDays(DateTime.LocalNow(),-30)),10),"/","-") & "T00:00:00.000Z",
And calling this as a variable but because the string does not come with quotation marks it gives a syntax error when the variable is called in the 'Source = ' line.
Well, first you want
= Date.ToText(Date.From(Date.AddDays(DateTime.LocalNow(),-30)), [Format="yyyy-MM-dd"])& "T00:00:00.000Z"
since that returns 2022-09-28T00:00:00.000Z while yours returns 9-28-2022 T00:00:00.000Z which does not seem to be the original format
then try out this, which I cant test
let variable = Date.ToText(Date.From(Date.AddDays(DateTime.LocalNow(),-30)), [Format="yyyy-MM-dd"])& "T00:00:00.000Z",
Source = Json.Document(Web.Contents("https://api.crewhu.com/api" & "/v1/survey?query={""_updated_at"":{""$gte"":"""&variable&"""}}", [Headers=[X_CREWHU_APITOKEN="xxxxxxxxxxx"]]))

I'm trying to create a spline chart using this CSV:

As you can see here [IMAGE], the graph is showing the date and time, but the x Axis is not accepting the date / time.
Ive tried using date.UTC, but that did not work either. Can someone point me in the right direction?

I see that date variable in your code is a string:
// all data lines start with a double quote
line = line.split(',');
date = line[1] + " " + line[2];
(...)
RTC.push([
date,
parseInt(line[3], 10)
]);
If you choose to construct the point's options as an array of two values and the first value is a string then it's treated as its name property (not x).
Explanation: https://www.highcharts.com/docs/chart-concepts/series
In that case Highcharts assigns subsequent integers as x values for all points (that's why there're values like 00:00:00.000 (1 Jan 1970), 00:00:00.001 etc.).
You need to parse your date to timestamp. You can use Date.UTC() (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/UTC) or some other function for this.
I've managed to get it working with Date.UTC using the following code:
var yyyymmdd = line[2].split("-"); //Split the date: 2017 12 16
var hhmmss = line[3].split(":"); //Split the time: 16 11 14
var date = Date.UTC(yyyymmdd[0], yyyymmdd[1] - 1, yyyymmdd[2], hhmmss[0], hhmmss[1], hhmmss[2]); //Stitch 'em together using Date.UTC
Hi there seems to be plenty out there to convert a US formatted date (MM/DD/YYYY) to a UK date (DD/MM/YYYY), but I'm trying to do the opposite: i receive a load of UK dates (DD-MM-YYYY) from the server which I'm trying to format as DD-MMM-YYYY (eg: 11 Jan 2013 ), but Flex thinks it's trying to convert American days and so when it gets 17-02-2013, it returns an empty string because there is no month 17.
How do i tell it I'm giving it UK dates and not US dates?
Thanks in advance.
Short answer, you can't.
Longer answer, there's not enough information to determine the date format. As you saw, in some cases you CAN determine that the date is not valid for the expected format (17-02-2013 - since 17 isn't a valid month, it must be DD-MM-YYYY rather than MM-DD-YYYY), but for just under half of the dates you just can't tell (is 01-02-2013 supposed to be Jan 2 or Feb 1?)
If you DO know that the dates are supposed to be in a particular format, you can use DateField.stringToDate to parse the string:
var value:Date = DateField.stringToDate(dateString, 'DD-MM-YYYY');
OK, got round it in the end with this ugly hack: ended up converting the string into an array and re-organising it so that it would fit the american format before using the DateFormatter.format on the result. There must be a more elegant way...
<Script>
public convertDateStringToUS( date : String ) : String
{
var dateArray : Array = date.split( "-" );
var day = dateArray[0];
var month = dateArray[1];
var year = dateArray[2];
date = month + "-" + day + "-" + year;
return date
}
</Script>
<declarations>
<mx:DateFormatter id="dateFormatter"
formatString="DD-MMM-YYYY" />
</declarations>
<s:Label id="myDateLabel"
text =" { dateFormatter.format( convertDateStringToUS( date ) ) } "/>
I have a loop to select 'LibrarySwaps' for tomorrow.
This works, but not when I set days_ahead default to 1 (it returns records with todays date).
Why do I need to add 2 to the date to get a day than is only 1 day in the future?
I am doing this 11am EST so this is not a time zone issue with that and UTC both being the same day... I thought maybe 'cos one side has a time component and the other doesn't but nope, I'm using date() for the sql and Date + 1.days for the ruby. I may switch to (one date minus the other date) and look at the result.
Thanks!
Returns Tomorrows (uses 2):
def self.find_future_swaps(days_ahead=2)
#upcoming_swaps = LibrarySwap.all(:conditions => ['date(suggested_date) = ?',Date.today + days_ahead.day ])
end
Returns Todays (uses 1):
def self.find_future_swaps(days_ahead=1)
#upcoming_swaps = LibrarySwap.all(:conditions => ['date(suggested_date) = ?',Date.today + days_ahead.day ])
end
MySQL is likely storing your suggested_date field in UTC. So an entry from 10pm on 4/29 would actually be stored as 3am on 4/30 (assuming you're in the Eastern timezone).
You can do this to add the offset to the times you're searching for:
#upcoming_swaps = LibrarySwap.all(:conditions => ['date(convert_tz(suggested_date,'+00:00','-05:00')) = ?',Date.today + days_ahead.day ])
Is there any ActionScript class which represents "durations of time", similar to the TimeDelta class in Python?
Edit: Thanks for the responses. I should clarify a bit, though: I want be able to ask questions like "how many weeks are between date0 and date1" or "let x represent "one day". What is date2 + x?"
I know I can do all this by representing dates as timestamps... But I'm hoping to find something nicer.
I posted a full AS3 port of the .NET TimeSpan class on this question, which sounds exactly like what you need.
// 5 days from new
var ts : TimeSpan = TimeSpan.fromDays(5);
var now : Date = new Date();
var fiveDaysTime : Date = ts.add(now);
// Diff between dates
var d1 : Date = new Date(2009, 1, 1);
var d2 : Date = new Date(2009, 1, 6);
var ts : TimeSpan = TimeSpan.fromDates(d1, d2);
You can use time() in the Date class to get unix era milliseconds and use that for time delta.
If you subtract two dates:
var dateDiff = date1 - date2;
dateDiff will hold the number of milliseconds between the two dates. You can then convert from milliseconds to whatever useful number you like.
I don't think there is a class which measures change in time in Actionscript 3. According to this blog post on Adventures in Actionscript, timing is very inaccurate in the Flash player on the web. That post is pretty informative and has a class called SuperTimer that might help you. You might want to keep this inaccuracy in mind if using solutions posed by Justin Niessner and toastie.
