Java and JavaScript timestamps are not the same - Stack Overflow

I've got a problem with timestamps between java and javascript.

I already found these 2 questions about the timestamps and I know about the timechanges all over the years.

Timestamp deviation Java vs Javascript for old dates (3600secs)

Why is subtracting these two times (in 1927) giving a strange result?

Basically at midnight at the end of 1927, the clocks went back 5 minutes and 52 seconds. So "1927-12-31 23:54:08" actually happened twice, and it looks like Java is parsing it as the later possible instant for that local date/time.

What the problems makes is that when I have javascript and put the timestamp in there then I get an other date than the Java date. I need this to show the correct date on the webpage. I know I can request the date as a string but I prefer using a timestamp.

Java date 0001-01-01 timestamp is -62135773200000

JavaScript date 0001-01-01 timestamp is -62135596800000

The difference is -176400000; 49 hours.

Does anybody know what I can do for this.

Personally, I would avoid passing numerical timestamps around from a system in one language to a system in another language for the sole reason that the languages may differ in the algorithm they use to generate them.

There is an international standard in place (ISO-8601) to deal with passing timestamps from system to system. In this your date representation bees 0001-01-01T00:00:00+00:00. I would remend using this approach, as it's a widely accepted solution for this very problem.

This might be related to TZ and DST settings which diverge from browser to java. In order to nail it down, I remend to use ISO-8601 formats like 2008-02-01T09:00:22+05, this is ambiguous-less
