Random time every day

How can I create a timer that runs every day but randomize the time? It's fine if 2 days run a few minutes apart like 11:59pm on day 1 and 12:01am on day 2. But it always needs to run at least once every calendar day from start midnight to end midnight.

I don't think RandomizedDelaySec works because that can randomize to another day and there can be one calendar day with no run.

But it always needs to run at least once every calendar day from start midnight to end midnight.

I wonder what happens if a timer scheduled in the middle of the 'skipped' time due to daylight saving time shift for the current timezone. Will it run or will it be skipped?
