I am considering using shepherd timers as crontab replacement. But I

want to first make sure they work correctly on time, timezone and

daylight-saving changes. In my experience with systemd, it can truly

be a minefield, e.g.

the day of DST change

for entire hour after DST change

wrong timezone

leads to its spurious trigger

I also recall many bugs with RandomizedDelaySec, but shepherd and cron

have no equivalent feature, so ignoring that.

Can someone confirm that shepherd timers do not have the same bugs?

And if so, make a note about that in the user manual? Thanks.
