Guys,

I'm sure there is a solution for this:
When I schedule a daily job to run at 1:30 AM and we switch from Winter to
Summer time, the job doesn't run, because when the clock reaches 1 AM it's
suddenly 2 AM and 1:30 AM never happens.

The same job would run twice, when we switch back because when it's 2 AM, it
has already run 30 minutes before, but then it's suddenly 1 AM again and
it'll run again in 30 minutes.

For simple clean-up jobs, this might be acceptable, but when running more
complex jobs that need to run once and only once per day, this isn't going to
work too well.

Any ideas?

Use UTC on all your servers, set local time zone inside your shell (assuming you care). Daylight saving is really a convention for people not machines anyway.
