We can't get a zero (e.g. no 0:00), but we can get a 1 (e.g. 1:00 or 10:00).
1 + 0 + 0 = 1
1 + 0 + 0 + 0 = 1
(The maximum possible would be at time 9:59 --> 9 + 5 + 9 = 23)
Answer:
The smallest possible sum of the digits is 1.

if you only have the '12' to indicate noon and midnight,
12
then there are clocks with 3,6,9, and 12
30
if the problem is to add 1 through 12
12(12+1)/2
6(13)

Smallest possible sum is 1, which occurs at 1:00 or 10:00
