Dear friends,
I have a bunch of entries in my crontab, all doing different things at
different times. These times are picked up by the computer clock.
However, one particular task (downloading weather maps) would benefit if it was
set to download using a clock that does not spring forward and fall back. This
is because these maps appear to be released according to GMT/UTC and so setting
the time according to the local clock does not quite work. (I am aware that I
could set my cron job to be at a specific hour later than the actual during
standard time, but I figured that this would be a good opportunity to get to
know of such a possibility, if such exists.)
So, how do I make a single entry that uses GMT or UTC, in my crontab? While
also using the local time for the other tasks on crontab?
That sounds ideal for a systemd timer since it has native support for
UTC. You'd need a .service to fetch the weather maps and a .timer to
trigger the .service. As far as systemd goes that is pretty basic.
Everything else would stay under cron.
