I've got a small fun puzzle for you.
It has me 100% stumped! After 2-hours of trial-and-error + Google searches, I'm asking for help :)
Timestamp:1393878630947498
What is the excel formula to convert that to a Date/Time?
I know for a FACT the actual Date/Time is: May 9, 2017, 10:21 PM
Many thanks!
Take the big integer and multiply it by:
0.000000000030752269457537
then format the product as date/time
NOTE:
This simple relationship is only valid if the two time/date forms have the same starting point.

I'm working with JSON, but I am somewhat new to it.
I'm trying to pad numbers to two characters because that makes the whole thing a lot easier and more uniform.
However, this makes numbers less than 10 throw the error "Expected comma".
Can someone please explain to me how to solve this/what the best workaround is?
Thanks!
From json.org:
A number is very much like a C or Java number, except that the octal
and hexadecimal formats are not used.
Numbers like: 01, 02, ... are not allowed.
I'm getting some very odd looking timestamps from netflix's video API, they look like this ;
527637852762
I assume its a timestamp as in the json it looks like this,
"time": 527780548207
How can I convert this ? it should equate to around some day in September 2017.
So far I've tired dividing by 100, 1000 and no luck.
Thanks
Seconds since 1.1.1970?
It is a common unix time stamp
Referring to the Netflix API documentation they say:
For times since the epoch both seconds and milliseconds are supported because both are in common use and it helps to avoid confusion when copy and pasting from another source.
Milliseconds Timestamp to Date
I figured it out, its a 2001 timestamp. Seconds since 2001. So take that figure / 1000 and that converts correctly :)

I've gone through quite a few examples on here and I apologize if I'm asking a repeat question, as far as I can tell, I am not.
I have an SSRS report made that shows gross sales for certain aspects of our sales departments. They are broken down, in row, by "cost, gross profit, gross profit %, order count, total sales." The columns are the aspects of our sales. Web sales, phone sales, etc....
In the tablix I can format a text box to display the results as numbers, but as you can see, I have also Percentage and Count in there. I don't know how to format those within the context of the original text box format. So I know I have everything that shows under there as a number already, but how do I handle getting the percentage to show as a percentage and the count to show as a count?
For example, all the percentages currently show as, "$0.35" and various other numbers that follow that form. The count's currently appear as currency too.
I've used an example I found on here, "=Iif ( Me.Value = Floor ( Me.Value ) , "0%" , "0.00%" )," but all that did was make everything that showed up in that column, "0.00%" I am fairly new to SSRS and have been cramming consistently for the past two weeks, but I just cannot find help on this. Thank you in advance for anything you can offer.
Update: =IIF(Fields!LVS_Web.Value=0.00, "0%", format(Fields!LVS_Web.Value, "P"))
That worked... to a degree, but now everything is a percent.... thinking ELSE here but I don't know how ELSE goes in, I've not once seen the word ELSE.
Update 2: The thing that I've noticed is that in the statement, where it says, "=0.00, "0%"," that doesn't even really apply. I've just put that there because I'm new to this and I just needed an argument involved. I took the 0% and changed it to N under the condition that the number was < .99, hopeing I would just catch all of the decimals that fell below the value of 1. Like, "$.23", which later became 23.45%, so I COULD do that, but what I don't udnerstand is it made everything else, "N," instead of a number. Why is that? It doesn't make everything else, "P?"
I'm losing my damned mind.
There is also the fact that this is information being pulled from a stored procedure, I don't really know too much about those quite yet, I get assigned simple tasks ever so often as a stepping stool for learning. I don't really know what the query was, but I couldn't edit it if I wanted to. This can be done with expression formatting but my expression is too broad, but I get mixed results using Greater or Less than, and it's probably not the wisest thing to use since these numbers are not set in stone. My day is almost done, I've made very very little progress, but I had a good lunch. So success.
So I provided my own answer for this problem, and it works. Thanks me. Thanks to all the tried to help me and did help as well. I appreciate the effort strangers will put out for each other.
I've had a new problem develop, I need to display a time relative to the data being pulled. I can put NOW in there and get today's date, but if someone is pulling information from FEB, they may be a little off-put by the current date. I'll probably get this figured out soon, but if anyone can help in the meantime, I would appreciate it.
A standard principle is to separate data from display, so use the Value property to store the data in its native data type and use the Format property to display it how you want. So rather than use an expression formatting the Value property such as =Format(Fields.SomeField.Value, "0.00%") leave the Value as =Fields!SomeField.Value and set the Format property to P2.
This is especially important when exporting your report to Excel because if you have the right data type for your data it will export to Excel as the right data type. If you use the Format function it will export as text, making sorting and formula not work properly.
The easiest thing to do to control the formatting is use the standard numeric formats. Click on the cell or range of cells that you want to have a certain format and set the Format property. They are a format specifier letter followed by an optional digit for precision (number of decimal places). Some useful ones are:
C Currency with 2 decimal places (by default)
N4 Number with 4 decimal places
P0 Percentage with no decimal places
Click on the link above for the full list. Format the number cells as numbers and the percents as percents - you don't need to try to make one format string fit every cell.
These standard numeric formats also respect regional settings. You should set your report's Language property to =User!Language to use the user's regional settings rather than the report server's.
If the number is already * 100 eg. 9.5 should be shown as 9.5% then use the format:
0.00\%
9.5 -> 9.5%
0.34 -> 0.34%
This way you can use the standard number formatting and just add the % to the end. The \ escapes the %, preventing the *100 in formatting (which would make 9.5 show 950%.).
=iif(Fields!Metric.Value = "Gross Profit %",
Format(Fields!LVS_Web.Value,"P"),
iif(Fields!Metric.Value = "Order Count",
Format(Fields!LVS_Web.Value,"G4"),
Format(Fields!LVS_Web.Value,"C")))
This is what saved me and did what I wanted. There is another error, but it's my bosses fault, so now I get to laugh at him. Thanks everyone.

This is simple to use,
Percent of (the sum of line item totals for the current scope)/(the sum of line item totals for the dataset).
This value is formatted using FormatPercent specifying one decimal place.
="Percentage contributing to all sales: " & FormatPercent(Sum(Field!LineTotal.Value)/Sum(Field!LineTotal.Value,"Sales"),1)
I have a timesheet application where people put eg. 3.5 hours worked in a day.
Sometimes someone might put 1.25 I guess.
I stored as float but am now having issues when I retrieve data... Should I have used decimal to 2 or 3 points?.
There are a few ways to tackle this.
If you want to have uniformity in the entries, I'd suggest using a "Fixed-Point Type" value (see more info here). This would mean that 3.5 hours should always be saved as 3.50.
The other option is to convert all your values to integer values (see more info here), and in your application layer, convert the values back to "readable" format. For example, you would store 1.25 hours as 125, and in your application layer, divide by 100, therefore getting 1.25. This method is more useful for currency management/calculation applications where a specific level of precision is necessary.
Floats allow for floating decimal point precision, so there is no restriction on uniformity of precision for decimal values...
For your purposes, I'd recommend fixed-point type unless there's complexity that you didn't mention.
Hope that helps.
The number 71867806 represents the present day, with the smallest unit of days.
Sorry guy's, caching owned me, it's actually milliseconds!
How can I
calculate the currente date from it?
(or) convert it into an Unix timestamp?
Solution shouldn't use language depending features.
Thanks!
This depends on:
What unit this number represents (days, seconds, milliseconds, ticks?)
When the starting date was
In general I would discourage you from trying to reinvent the wheel here, since you will have to handle every single exception in regards to dates yourself.
If it's truly an integer number of days, and the number you've given is for today (April 21, 2010, for me as I'm reading this), then the "zero day" (the epoch) was obviously enough 71867806 days ago. I can't quite imagine why somebody would pick that though -- it works out to roughly 196,763 years ago (~194,753 BC, if you prefer). That seems like a strange enough time to pick that I'm going to guess that there's more to this than what you've told us (perhaps more than you know about).
It seems to me the first thing to do is verify that the number does increase by one every 24 hours. If at all possible keep track of the exact time when it does increment.
First, you have only one point, and that's not quite enough. Get the number for "tomorrow" and see if that's 71867806+1. If it is, then you can safely bet that +1 means +1 day. If it's something like tomorrow-today = 24, then odds are +1 means +1 hour, and the logic to display days only shows you the "day" part. If it's something else check to see if it's near (24*60, which would be minutes), (24*60*60, which would be seconds), or (24*60*60*1000, which would be milliseconds).
Once you have an idea of what kind of units you are using, you can estimate how many years ago the "start" date of 0 was. See if that aligns with any of the common calendar systems located at http://en.wikipedia.org/wiki/List_of_calendars. Odds are that the calendar you are using isn't a truly new creation, but a reimplementation of an existing calendar. If it seems very far back, it might be an Julian Date, which has day 0 equivalent to BCE 4713 January 01 12:00:00.0 UT Monday. Julian Dates and Modified Julian dates are often used in astronomy calculations.
The next major goal is to find Jan 1, 1970 00:00:00. If you can find the number that represents that date, then you simply subtract it from this foreign calendar system and convert the remainder from the discovered units to milliseconds. That will give you UNIX time which you can then use with the standard UNIX utilities to convert to a time in any time zone you like.
In the end, you might not be able to be 100% certain that your conversion is exactly the same as the hand implemented system, but if you can test your assumptions about the calendar by plugging in numbers and seeing if they display as you predicted. Use this technique to create a battery of tests which will help you determine how this system handles leap years, etc. Remember, it might not handle them at all!
What time is: 71,867,806 miliseconds from midnight?
There are:
- 86,400,000 ms/day
- 3,600,000 ms/hour
- 60,000 ms/minute
- 1,000 ms/second
Remove and tally these units until you have the time, as follows:
How many days? None because 71,867,806 is less than 86,400,000
How many hours? Maximum times 3,600,000 can be removed is 19 times
71,867,806 - (3,600,000 * 19) = 3,467,806 ms left.
How many minutes? Maximum times 60,000 can be removed is 57 times.
3,467,806 - (60,000 * 57) = 47,806 ms left
How many seconds? Maximum times 1,000 can be removed is 47 times.
47,806 - (1,000 * 47) = 806
So the time is: 19:57:47.806
It is indeed a fairly long time ago if the smallest number is in days. However, assuming you're sure about it I could suggest the following shell command which would be obviously not valid for dates before 1st Jan. 1970:
date -d "#$(echo '(71867806-71853086)*3600*24'|bc)" +%D
or without bc:
date -d "#$(((71867806 - 71853086) * 3600 * 24))" +%D
Sorry again for the messy question, i got the solution now. In js it looks like that:
var dayZero = new Date(new Date().getTime() - 71867806 * 1000);
