Solved Wrong time but right timezone

J

jwz104

When I enter the date command it returns a time that is 2 hours behind. But when I setup my timezone with tzsetup I do choose the correct timezone. How can I fix this?
 
In Europe it is summertime now, and even in Greenwich the official time is not GMT but BST = GMT+1. In the Netherlands the time is CEST = GMT+2.
 
The point is that it could indicate the hardware clock is set to UTC while the system is not. Or vice versa.
 
Hey everbody. Since this thread isn't solved and I have investigated the same problem but couldn't solve it.
The Situation: I have a PC and a laptop. Both run the exact same FreeBSD 11-RELEASE. On both the CMOS-clock is set to UTC and they run the same timezone configuration.
I live in Norway so my timezone is set to
Code: 
setenv TZ Europe/Oslo
in my ~/.tcshrc. My timezone is +1 hour ahead from UTC.
When I type date on my PC ist shows the right time (UTC+1), but on my laptop it shows me UTC-time (-1 hour from my place).
I tried setting the timezone in /etc/login.conf instead of my shell's configuration, which also works fine on my PC, but does nothing on my laptop.
I then remembered that I maybe, during installation on my laptop, choose that my CMOS-clock is set to local time and started investigating...

As I said, the CMOS-clock on both machines is set to UTC. ps aux shows adjkerntz -i runs on my laptop, which is not the case on my PC.
Further is the sysctl machdep.adjkerntz variable on my PC =0 and on my laptop on =-3600 (which is 3600 seconds/24 hours).
I then killed the running adjkerntz -i on my laptop an then changed
Code: 
sysctl machdep.adjkerntz=0
machdep.adjkerntz -3600 -> 0

Still that made no difference and my laptop shows the wrong time.
I also couldn't figure out how the adjkerntz -i process gets startet (it's not from cron). I searched through some /etc/rc. files but there where
no differences between my PC and my laptop.
I would really like to understand how timezone and adjkerntz interact and what configuration is differnt when choosing CMOS is set to localtime during install.
Somebody who knows that?
Thanks!

When you choose local time, a file /etc/wall_cmos_clock has been created, to inform the system that your cmos clock is set to local time. To use a cmos clock set to UTC, delete that file.
 
That did it. Clock now showing right time! Thank you.
Removing /etc/wall_cmos_clock SOLVED it for me.
Since the TS fixed it using ntp, I guess this thread can be marked as solved.
 
For anyone wondering where the /etc/wall_cmos_clock is documented, it's right there in the adjkerntz(8) manual page:

Code: 
FILES
     /etc/localtime        Current zoneinfo file, see tzsetup(8) and zic(8).
     /etc/wall_cmos_clock  Empty file.  Its presence indicates that the
                           machine's CMOS clock is set to local time, while
                           its absence indicates a UTC CMOS clock.

The adjkerntz -i command gets called quite early during boot by an rc(8) script /etc/rc.d/adjkerntz as also described in the same manual page.
 
This solved my problem.

My case: one machine, three systems. Two clock were ok, my FreeBSD wasn't.
I've just created /etc/wall_cmos_clock in etc... done!
