Though the colon is already used for the time syntax for the 
opening_hours key: http://wiki.openstreetmap.org/wiki/Key:opening_hours
That's a fairly well used key, so it makes sense for the restrictions 
time syntax to be consistent.

Also, what if you don't know what time the school zone applies?
Around here, they usually just have a sign with "20 when lights flash" 
or similar. I assume its at typical school times, but how would I tag that?
