I do not know if garmin supports restrictions that are only in force
during certain hours. I have carried out web searches and found nothing
so far on that subject. If we had an example map (unlocked) that contained
an example of such a restriction we would have a chance to reverse
engineer it.

The restriction records in the map certainly have space for some more
flags/info but all the examples I have seen so far look the same.

Cheers,

Mark
