I connect to servers with non-local timezones every now and then... Let's add the timezone in clock meter to minimize confusion there.

I would at least make this optional (config option) as (... how do I say that politely ...) it is not a sign of following best practices to run distributed servers with clocks in local time zones.

Nah. It's about the display of the system time in UTC or in local time. Note the colck meter uses localtime_r already and not gmtime_r. But without the UTC keyword it can cause the user confusion.

The switch between local time and UTC can be done as a separate feature.

Whether or not the timezone being local on a server makes sense... Depends.

But that's the point: My workstation has local timezone CEST, and the server has UTC. Looking at the clock from server's htop shocked me for a little moment. 🙃

Will have a look to make it configurable.

I am confused how sysadmins would be confused about the TZ they set on their own user / their root user.
And why in ClockMeter.c but not in DateTimeMeter.c ?

Bring your TZ to the server. TZ="Europe/Berlin" htop works.
(so does fixing your ssh env 😄)

grep -r localtime
ClockMeter.c:   const struct tm* lt = localtime_r(&host->realtime.tv_sec, &result);
DateMeter.c:   const struct tm* lt = localtime_r(&host->realtime.tv_sec, &result);
DateTimeMeter.c:   const struct tm* lt = localtime_r(&host->realtime.tv_sec, &result);
Process.c:   (void) localtime_r(&this->starttime_ctime, &date);

That's all the code that would be affected by time zones. And yes, if you show the timezone offset in ClockMeter, it should also show in DateTimeMeter.

Well, my confusion was not about the settings of the server, but more about what terminal window I was looking at. 😜

Because that's what I use. 😁 Added it to date/time meter in another commit, but still without any configuration option.

I would have to add that in user configuration of any server... Using environment variables via ssh is a nice idea, but does not work out: This requires the server to accept these variables (see AcceptEnv and PermitUserEnvironment in sshd_config man page), and the default is to not do so.

TBH, all except TZ=UTC is just overrated …

... just as done in clock meter.
