I'm about to install a new system and just noticed that the BIOS time is set to UTC time. Should I set it to local time? What consequences does it have to leave it as is, or set it to local time?

The OS I'll be installing is Kubuntu 11.04.

If you leave it as UTC you'll get the correct time displayed in Kubuntu. –  boehj May 12 '11 at 12:41

Check what your setting in /etc/default/rcS are if it is UTC=yes then set it to UTC in your BIOS and Kubuntu will use your time zone file adjust it properly. The problem is if it thinks your BIOS is UTC and it's actually local time your hwclock is always going to be out of sync and when it uses timezone data like it would on a UTC clock you are going to end up with the wrong time.

I'll set it to UTC since the default is UTC=true (checked it in the initscripts package). Thanks! –  Lekensteyn May 12 '11 at 12:54
    
The Alternate CD asks me whether the clock is set to UTC or not. I don't believe this is the case for the Desktop CD. –  Lekensteyn May 13 '11 at 11:48

In most cases, I would recommend to set BIOS to UTC time. but if you dual boot with Windows. I would recommend local time. Windows does not properly handle BIOS-set-as-UTC. So everytime you switch OS, one screws other's time.

my two cents
