hwclock and slitaz handbook
-
Is the slitaz handbook http://www.slitaz.org/en/doc/handbook/system-admin.html wrong in the hwclock section?
it says
Syncronize the system clock to the hardware clock ( --utc = universal time, -l = local time):
# hwclock -w --utc
Syncronize the hardware clock to the system clock:
# hwclock -s --utc
hwclock --help says
Options:
-r Show hardware clock time
-s Set system time from hardware clock
-w Set hardware clock to system time
-u Hardware clock is in UTC
-l Hardware clock is in local time
-f FILE Use specified device (e.g. /dev/rtc2)
Aren't the -w and -s options inverted? Am i misunderstanding?
Should the doc be fixed? If yes am i allowed to do that? -
I think it should be the other way round, yes:
seawolf@sammy:~ $ hwclock -r
Sat Oct 16 09:42:59 2010 0.000000 seconds
seawolf@sammy:~ $ date
Sat Oct 16 10:43:02 BST 2010
seawolf@sammy:~ $ sudo hwclock -s
seawolf@sammy:~ $ date
Sat Oct 16 09:43:20 BST 2010
seawolf@sammy:~ $ sudo date +%T -s "10:46:00"
seawolf@sammy:~ $ date

The docs site is at http://doc.slitaz.org/en:handbook:systemutils#system-time which is slightly different but still has this issue. You can go ahead and change it; everything has a history so we can just revert it if need be later on.
Perhaps we should change it to say something like:-s syncs both to the hardware clock
-w syncs both to the system clock
Only mentioning the one that is considered correct, to avoid confusion.
Howdy, Stranger!
