That's the way to do it (and I am not sure this got fixed, but previously when you set it not to UTC you got a random offset ;-). Linux gets the hardware clock from its virtual TOD, and normally that's identical to the LPAR TOD, which is normally equal to the hardware TOD. They're all at UTC, which is good. CP uses the timezone to show local time in various CP things, and CMS indirectly also uses the CP local time for its stuff. This does not influence Linux in any way. Applications in Linux use (through the glibc runtime library) the /etc/localtime definitions. These definitions define the offset between local time and UTC, as well as the cut-over time for DST. Many applications in Linux don't really need to care about whether time is jumping backwards, so they will simply convert the Linux system time (UTC) to local time with whatever the current offset is. Things that do care (e.g. to measure delays) will measure in system time to assure they have a time that is incremented consistently. Things that care a lot (e.g. file systems) will record the system time as well as the offset or time zone. This is what I got when I was creating a new file every second: linux10:~ # ls -l --time-style=full-iso file* 30 2004-10-31 02:59:57.000000000 +0200 file60.tmp 30 2004-10-31 02:59:58.000000000 +0200 file61.tmp 30 2004-10-31 02:59:59.000000000 +0200 file62.tmp 29 2004-10-31 02:00:00.000000000 +0100 file63.tmp 29 2004-10-31 02:00:01.000000000 +0100 file64.tmp 29 2004-10-31 02:00:02.000000000 +0100 file65.tmp Now as far as I recall the rmfpms gatherer is keeping the archive in files that are named after the local time, so you'll probably lose your data in 6 months. Since it's in the middle of the night, you may not care too much about it.
