You can know the answer for a given program whose code you are familiar with,
but there is no definitive answer otherwise.

Here's my take:

Programs which depend on a changed library or whose binary was updated need to
be restarted.  They'll continue using the old code until reloaded.

Programs which read timezone information themselves and store it will need to
be restarted.

Programs which store a coming date of time change will need to be restarted.

Programs which just make time calls should be OK.  If they handle time
changes at all in the first place, the fact that the time change is occurring
on a different date shouldn't affect them.
