The requirements sound a bit fluffy to me.

Any time-displaying application will find out the new time next time
it reads the time. So afaict this is only really useful for clock
applets which display once per minute, so they will show the new time
promptly after the time was altered, yes? Is that really worth adding
new code for?

hm. Why? What are you thinking of here, specifically?

Also... what's the story with kernel-NTP updates?
