Cannot use Joda for Android UnitTests

[AZOM]

I am trying to write UnitTests that deal a lot with DateTime and wanted to make them work in all time zones. Therefore I wanted to create DateTime objects which represent a relative timestamp from a given UTC timestamp.

However all my times are missing a date and have a funny time.

My UTC timestamp is:

private static final long SESSION_START_UTC = 1547222580L; //Fri, 11 Jan 2019 16:03:00 UTC

My Joda DateTimes all look like:

get24hStringLocalTime.dateTimeUtc = 1970-01-18T21:47:02.580Z
get24hStringLocalTime.dateTimeDefault = 1970-01-18T22:46:02.580+01:00

So the conversion from UTC to local time works, but the time itself is wrong and also the date is wrong.
I assume this has something to do with a missing JodaTimeAndroid.init(this); - but how can I do this in a UnitTest?

I did a mistake myself and forgot to multiply the timestampUtc by 1000 (because it is in seconds)
