Someone in Australia could send a file with a DOS timestamp to somebody in California across the Internet, and the recipient will see a file that appears to be written ``in the future''. I don't see how adjkerntz should fix it. Since DOS files don't have an explicit timezone, you can imply any time zone you want, so applying the kernel's idea (UTC) seems to be most logical. (Note that this might conflict with the idea of your local DOS, but applying the localtime does as well conflict with the idea of any other DOS not running in *your* localtime zone.) To be honest, even in cases where i run DOS every now and then, i simply don't care for its broken idea of a timezone. I live with it running in UTC then.

DST rules: MET How to reproduce: setup localtime as MET, and tweak your clock to run from Mar 31, 1996, 01:58 MET onwards. Watch the syslog at 02:00 MET (where the switch happened to 03:00 MET DST). I think Holm Tiffe was willing to send you all information he's got. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
