How many times do the digits of a digital clock add up to 6 in a 12 hour period?

The short answer is "27" and we have to make a number of assumptions because the question as described enough is vague.

So let us assume:
- we are only considering a clock displaying HH:MM where HH is hours and MM is minutes.
- we start the 12 hour period at 00:00 (midnight).
- we must add all 4 digits individually.  So 11:11 is 1+1+1+1 not 11+11
- The sum of all 4 digits must equal 6
