1 Hello everyone,
2
3 I recently had to reset my clock to a more "correct" (that may be subjective) setting.
4 In your case I would set my /etc/conf.d/clock file as:
5
6 CLOCK="UTC"
7 TIMEZONE="US/Pacific"
8
9 then I would assure that my /etc/localtime file is correct with the next command:
10
11 $ cp /usr/share/zoneinfo/US/Pacific /etc/localtime
12
13 If you have no zoneinfo files then consider emerging 'timezone-data'.
14 The setting like that should be fine and if you have an offset it's that your hardware clock
15 must be set to a time that is considered as UTC (since you have "CLOCK=UTC" in your conf)
16 while it's not.
17
18 So set your clock correctly with rdate, ntp whatever...
19 and then write your system clock to your hardware clock (I guess this action is done at shut down).
20 You may use the following command :
21
22 $ hwclock --systohc
23
24 Then your machine is ready to have correct time as UTC. Be sure to have your profile
25 environnement variable TZ to be set to your timezone. In your .profile :
26
27 export TZ="US/Pacific";
28
29 Concerning dual boot.. as I am in !! Everywhere I could see advice to set my CLOCK var to "local"
30 but that's always a mess with the timezone... so the simple thing is to deactivate the Microsoft Windows
31 update or at least to set it to UTC time..
32 Thus keeping CLOCK="UTC" which would be a quite good standard.
33 But I understand Gentoo is installed to cause no harm to Windows, thats why there is this CLOCK="local" attitude
34 I guess.
35
36 Hope that helps
37 I'd be happy to share the pros and the cons...
