This may not be a big deal for smaller shops that only have one or a few site, but for larger organizations this is something I'm curious about.
What are the pros and cons have having all/most of your server in UTC? It would certainly help in reporting and centralized logging. Also with event correlation for troubleshooting or security auditing. One also wouldn't have to worry as much about Daylight Saving Time changes.
One disadvantage could that scheduling automated events (e.g., cron) may take a bit of may if you want it to run something at "4 AM" in the local, geographic time. For Unix-y machine you could still have users be in the local timezone by setting "TZ" in /etc/profile, but for Windows users that RDesktop into a server (for whatever reason), are they stuck with looking at UTC?
