What is the hardware clock set to right now? (one sure way to find out is to boot to the BIOS' setup screen) You want the above parameter to match the actual setting of the BIOS clock. Note that the BIOS clock is unaware of timezones. If you do not live in UTC and you want your BIOS clock set to UTC (recommended) then the clock setting in the BIOS config screen will not be local time. | But...Now, my question is, what are the advantages of the UTC time? | Do you know where can I get more info on UTC time and why I should use | it? UTC is simply a time zone (formerly called GMT). It is +0000 offset from UTC. My, current, local timezone (EDT) is -0400 offset from UTC. When I moved from New York to Illinois (US/Eastern to US/Central) my clock was still correct. By using that as the reference point, all I had to do was run 'tzconfig' and tell the system that US/Central is now the local timezone. Everything just worked. The system clock didn't change, the BIOS (hardware) clock didn't change, but my displays now showed the correct local time. When I moved back I reran tzconfig and set the local time zone. All is (and was) well. Not to mention, by storing UTC instead of local time, no clock updates need to be done for daylight savings time switches. I laugh everytime someone's Windows machine says "I just updated the clock, is it correct?". -D -- One OS to rule them all, one OS to find them, One OS to bring them all and in the darkness bind them, In the Land of Redmond, where the Shadows lie. www: http://dman13.dyndns.org/~dman/ jabber: dman@dman13.dyndns.org
