http://en.wikipedia.org/wiki/Unix_time http://en.wikipedia.org/wiki/Talk:Unix_time These _might_ help you understand this confusing subject. For me they just gave me a headache. The best I can tell POSIX handling of time-keeping is just broken. In short, don't worry too much about it. If you really want to know what time it is use GPS time (a sane TAI-based system), then convert that to UTC. Jonathan Kollasch
