Dmitry raises some issue which I'm sure the ARG are looking at but you
_might_ be perfectly ok if all you're doing reading log files, etc and
not actually trying to combine this with a clock your program is
reading and expecting them to tie together with the time on your wrist
watch. And if your log didn't come from a run over summer-time
changes, leap seconds etc on an OS that actually dealt with such
things.
