Java Long Date does not convert to time in query editor

[AlbertMaes]

Hi there,

new to the forum and new to data modelling...

I am connecting to a PostGres Database of our ticketing system (ManageEngine ServiceDesk) where timestamps are stored in what i assume to be a java long date format.

The field CREATEDTIME (when a ticket was created) has a value e.g. 1530272032346 which equates to Friday, 29 June 2018 11:33:52 o'clock UTC according to the following website http://www.fileformat.info/tip/java/date2millis.htm

When I try to convert the number using the data type selector in the query editor, it seems that the system cannot interpret this number as a date and returns errors. 

Only if the value is 0 (e.g. in a RESPONDEDTIME field on a ticket where no response was logged yet) it returns 30/12/1899 00:00:00 +01:00

Tried all sorts of settings with regional settings, locale settings etc and have not managed to convert.

Can anybody give me a hint as to what i need to do?

Kind regards

Albert

hi,@AlbertMaes

   You can add a calculate column when you modeling like this

Date = DATEVALUE("1970-1-1") + (Table1[Column1]/(60*60*24*1000))

Result:

Thank you Lin!  Works a treat!!

I did some more digging here and it seems that indeed my database churns out Java Date Stamps (Day 0 = 01/01/1970), PowerBI seems to expect SQL Date Stamps (Day 0 = 12/12/1899)

How do I tell PowerBI to use a different date stamp?
