please help me for javascript code

I have to count down the system clock according to two different times. in hours, minutes, seconds. For example, a day is 24 hours.

Between 15:00:00 and 13:00:00 = 22 hours. When the clock is 15:00:00, it should count back from 22:00:00. and it must be 00:00:00 at 13:00:00.

Between 13:00:00 and 15:00:00 = 2 hours. When the clock is 13:00:00, it should count back from 2:00:00. and it must be 00:00:00 at 15:00:00.

i want it to repeat daily.

I've tried so hard for a few days, but I couldn't. please help me.

I add it again with the code I used.
