   Odd thing I noticed this morning, my ZFS scrub didn't happen over the weekend as it usually does.

   So I started to investigate. #nixos

   This didn't end up where I expected.

     So I looked at the timer itself.

     The definition is:
     ```
     [Timer]
     OnCalendar=Sun, 02:00
     Persistent=yes
     ```

     Right, now it's obvious, 02:00 didn't happen this last Sunday. 01:59:59 -> 03:00:00.

     So... yeah, I don't know what I expected but I didn't really expect it to skip it. This isn't a complaint or a bug. It's just another realization of why #DST is terrible.

     #nixos #systemd

     So to investigate this, I started by checking the status on the service. Last run was the weekend two weeks ago and hadn't been triggered since.

     So I did a `systemctl list-timers`, last scheduled run was two weeks ago, next is this Sunday.

     So why did it skip this Sunday?

     #nixos #systemd

     @sa0bse I’ve seen similar stuff happening. The price of DST is not zero.

     Out of sheer curiosity, the computer in question whas not configured to run on UTC then?

     @giffengrabber Not on UTC no. I should probably change that.

     @uint8_t Yes, I've also realized that everything 02:00:00 -> 02:59:59 would run twice within an hour once a year.

     @sa0bse if I were me, I would never schedule tasks to run between [02:00:00, 03:00:00]

     @sa0bse or another argument for using UTC on servers...
