I haven't had to deal with this for years, but if memory serves, there's
a place where you can tell Linux that the hardware clock is in local
time, not UTC.
Ah, yes, there is. You can select the mode when you install the system,
but the "system-config-date" utility offers a tickbox. By default, it's
ticked and that means "System clock uses UTC".
I also haven't done it in a while. This machine is F28, but started
life as F18 and has been continually updated since then. The same is
true for my other personal systems (they're current F28 or F29 and
started as F20 or earlier). For the last 25 years or so, 95% of the
machines I set up or use are Unix-esque in flavor, so I pretty much
always set up UTC on the hardware clock. Sort of second nature.
Well, I'm just installing an F29 MATE VM and on the TIME&DATE screen there is no tick-box
to indicate that the HW clock is or isn't "local".
Additionally, I could find no trace of "system-config-date" in F29.
[root@meimei ~]# dnf whatprovides *bin/system-config-date
Fedora 29 - x86_64 - VirtualBox 2.8 kB/s | 6.9 kB 00:02
Failed to synchronize cache for repo 'virtualbox', ignoring this repo.
Error: No Matches found
And you're right. It appears mine is from....(holy kapok!) F24! I told
you these machines have been updated from older versions.
Ok, so you can wait until chronyd syncs, then delete the /etc/adjtime
file and "sudo hwclock -w --utc" to set it to UTC (default unless the
last line of /etc/adjtime is set to "LOCAL").
I've checked my etc/adjtime and it has the last line set to local. I
also can't see anything obvious in that file to indicate the offset from
local to GMT so how does hwclock know what offset to use?
Also when I issue the hwclock command, it tells me my timezone is
GMT+11, which is correct for daylight savings time. Given that I can't
find any setting in KDE->System Settings any more to tell Fedora to
allow for daylight savings time, and noting that the hwclock is correct
for local daylight savings time, nor can I find any settings to specify
a Network Time Clock any more that would adjust the time accordingly,
how is my clocks correct for daylight savings time, or is the fact that
I'm tri-booting with windows causing the clocks to be correct?
I've done a check for system-config-date and it doesn't exist on my F28
system either, but then I did in the past have to re-install F26 from
scratch, so that may have removed it.
regards,
Steve
