I assume you mean a digital clock and that it only displays hours and minutes, not seconds. I'll also assume it's set to standard AM/PM time, not 24 hour time, which would be a bit different.
The times that would display exactly three 1s are:
That's 17, and they would be displayed 2x per day each, so 34 minutes in total.
A 24 hour clock displays digits whose sum total equals the number of led's used to display them 94 times a day. A 12 hour clock displays them 108 times a day.
On an analog clock with a 12-hour face: 44 times. On a digital clock: zero. (No needles.)

Exactly 55 times
Exactly 24 times.

press the clock button three times. :)
In military time, there are 24 hours in a day. To determine how many times the clock will display three or more of the same number in a row, we need to consider the possible patterns. There are four patterns where the clock will display three or more of the same number in a row: 00:00-00:02, 11:11-11:13, 22:22-22:24, and 33:33-23:35. Therefore, the clock will display three or more of the same number in a row four times over the course of one day using military time.
It is unknown exactly where a clock comes from. The first clocks were called sundials and they have been used since ancient times.

A broken clock is correct twice a day. This is because a clock with hands that are stuck will still display the correct time at least twice a day when the hour and minute hands align with the correct time.
On an analog clock with a 12-hour face: 44 times. On a digital clock: zero. (No needles.)
