One problem with the daylight savings is that they mess with reporting
tools that use timestamps. I guess an application could be configured to
log UTC instead of local time, but that's not always doable.
Also, if you have servers in several different timezones, it's better if
all systems follow the same clock.
So, I'm thinking it's perhaps better if I just use ZONE="UTC" on all
systems. These are the steps I can think of so far:
- make sure the BIOS clock is set to UTC
- run timeconfig and make sure "System Clock uses UTC" is checked
- cp /usr/share/zoneinfo/UTC /etc/localtime
- edit /etc/sysconfig/clock and set ZONE="UTC"
- reboot
Voila - instant UTC clock. Never need to worry about daylight savings again.
Anybody can think of any problems with:
- the procedure I described?
- the simple fact of using the "true" UTC timezone?
