First off, I apologise if this has been discussed/solved before - I did search the forum before posting.

Next, some background info. I recently bought a new Acer Aspire V5-573G (in case this is relevant). I did a fresh Gentoo installation, initially with OpenRC, but then I switched to systemd just to try it out. I have an older Dell laptop running Gentoo, which still has OpenRC. A millenium ago I had a dual boot with Windows on the old laptop, and so I had (and still have) clock="local" in /etc/conf.d/hwclock. I never had any troubles with these clock settings, so I ported them to the new laptop. Then I decided to switch to systemd on the new laptop, but when I tried to set the clock to "local", timedatectl complained that this is not fully supported and can be tricky with DST. So I went with the recommended UTC, and that's where the problems began.

In a nutshell, both UTC and local time are wrong on boot. I live in Australia, and the local time is currently GMT +1100, but here is what I get when I boot the laptop (the actual local time is 8:34 on 26 Feb).

Code:


# timedatectl

      Local time: Tue 2014-02-25 21:34:52 EST
  Universal time: Tue 2014-02-25 10:34:52 UTC
        RTC time: Tue 2014-02-25 21:34:51
        Timezone: Australia/Sydney (EST, +1100)
     NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: yes
 Last DST change: DST began at
                  Sun 2013-10-06 01:59:59 EST
                  Sun 2013-10-06 03:00:00 EST
 Next DST change: DST ends (the clock jumps one hour backwards) at
                  Sun 2014-04-06 02:59:59 EST
                  Sun 2014-04-06 02:00:00 EST


Running ntpd -s sets things right...

Code:

# timedatectl

      Local time: Wed 2014-02-26 08:35:10 EST
  Universal time: Tue 2014-02-25 21:35:10 UTC
        RTC time: Tue 2014-02-25 21:35:09
        Timezone: Australia/Sydney (EST, +1100)
     NTP enabled: yes
NTP synchronized: no
 RTC in local TZ: no
      DST active: yes
 Last DST change: DST began at
                  Sun 2013-10-06 01:59:59 EST
                  Sun 2013-10-06 03:00:00 EST
 Next DST change: DST ends (the clock jumps one hour backwards) at
                  Sun 2014-04-06 02:59:59 EST
                  Sun 2014-04-06 02:00:00 EST



...but only until the next reboot, when everything goes back to chaos. I checked the BIOS clock and it shows the correct UTC time, so something somewhere is not setting the system clock correctly. /etc/localtime is correctly symlinked to /usr/share/zoneinfo/Australia/Sydney, I even re-emerged sys-libs/timezone-data and recreated the symlink. These are the things I have tried so far, to no avail:


  • hwclock -w
  • hwclock --set --u
  • hwclock --date
  • timedatectl set-time
  • timedatectl --adjust-system-clock
  • timedatectl set-local-rtc 0
  • Switched back to OpenRC, set clock="UTC", clock_systohc="YES" and clock_hctosys="YES" in /etc/conf.d/hwclock and rebooted. Same result.
  • Selected RTC_HCTOSYS in the kernel (and of course ran make && make modules_install and copied the new kernel into /boot). Same result.
  • Selected all the RTC drivers in the kernel as built-in (including RTC_DRV_CMOS, which was selected by default anyway). Same result.


I also tried chanting and voodoo, but it didn't help either. Anyone who may have the slightest idea as to why this is happening, please let me know. Here is some system info:

I'd look into custom init scripts that may be futzing with the clock.

Your RTC looks right though? It appears to match UTC which is what you intended, but for some reason on boot, it's reading it and assuming it's localtime...

IIRC on my systemd install it looks like it's correct, I better check, maybe I have the same problem...

Thank you for the reply, eccerr0r.

It's a fresh install, so I have no custom init scripts. Besides, OpenRC init scripts shouldn't interfere with systemd, should they? In any case, the problem persisted when I switched temporarily to OpenRC, so I don't think it's related to the init system at all. The machine is new and the CMOS clock is perfectly accurate, so it's not a hardware problem either. And yes, you are right - for some reason the hardware clock is assumed to represent the local time and the universal time seems to be calculated from that. Very odd.

systemd's handling of clock is a mess and - as most things of systemd - you cannot replace it with other tools of your choice.

RTC Time and universal time displayed are the same: This is good.

Setting RTC_HCTOSYS in kernel is probably a good idea, so you need not rely on systemd to do this. In openrc, set clock_hctosys="NO" (because it should be done by the kernel).

Once the time is fetched correctly from the net, remove /etc/adjtime and call
Code:
hwclock --systohc --utc --noadjfile
You might also write a systemd service which runs this command automatically on shutdown. (Putting clock_systohc=YES should do a similar thing for openrc)

mv, thank you for the feedback - you nailed it. I looked around again and found this:

https://forums.gentoo.org/viewtopic-t-936216-start-0.html

Seems like a variation on a theme. I followed the suggestion to set clock_hctosys="NO" in that thread, switched back to OpenRC et voilà, lo and behold, the time was correct. This is essentially what you suggested too. I do have RTC_HCTOSYS in the kernel.

So I've switched back to good ol' OpenRC for the time being. Not sure why this is not given more attention, it's a rather annoying and obscure problem. Not sure if it's relevant, but in that thread above, there is a link to a bug that seems to be mostly ignored:

https://bugs.gentoo.org/show_bug.cgi?id=434410

Marking as solved, although I'm still not sure what exactly the problem was.
