We did C programs for a living and had a mix of Windows boxes and Linux boxes. Windows boxes were "naive" and had local time. We had a time zone with summer and winter time. On time transitions, all hell broke loose with Makefiles, which look at file time stamps :-) We ended up setting the Windows boxes to Monrovia/Liberia: no time jumps *and* (more or less) GMT. No more hassles... Cheers -- t
