Yes... But I have no Windows (except an XP _home_ sold with my old
laptop) so the RTC was in UTC. But termrc was timesync'ing with
"-L"---and I don't thing I even deal with this, since I played with a
total re-install when finding how to install Plan9 without a CD reader
or network (installing it from another OS already installed on the
disk).

What I still don't get is precisely how the fileserver could have the
right time, when the date displayed by the shell was wrong. It they both
use the same source (the kernel) how can this happen? Except that termrc
hence timesync(8) is run after the fileserver are launched, and then
are taking rtc but correcting it with the timezone (and perhaps the -L),
meaning that the fileserver will always use the time served by the
kernel from the RTC as UTC, while later program will use an user
specification to interpret the RTC.

The "-L" is a Windows thing but is in userland modifying a value that is
taken as is before userland is run...
