I've just learned that Java uses 64bit signed integer with ms units and uses the 1970 epoch. It covers +/-290 million year time span. The interesting thing with this format is that you don't need any special library to do time operations. For time stamps nanoseconds is in my case preferable. Thanks for taking the time to comment on this issue. It has been very useful.
