How to get GPS Time and TAI time in Java?

Question

Is there a way to get the current GPS time and TAI time?

( System.currentTimeMillis()'s return value is POSIX time, which isn't a linear representation of time. )

Answer 1

Your option is to look at the ThreeTen project, which is the reference implementation of the JSR-310 (new Java Date and Time spec). You can find a TAIInstant class in the javadocs

It's claimed to be still in alpha, though
