Solution:

In a clock.

Explanation:
1300 + 20 = 1:00PM + 20 minutes = 1:20 PM

1400 - 40 = 2:00PM - 40 minutes = 1:20 PM

Solution:

24 strikes - One Striker every hour

156 Strikes - Strike depends on the number of hours
(3rd hour - 3 strikes, 11th hour - 11 strikes)
Total Strikes = 2(1+2+3+4+5+6+7+8+9+10+11+12) = 156.

180 Strikes - 156 from previous + 24 (one strike every hour)

228 Strikes - 156 Strikes(Strike depends on the number of hours) + 72(24*3, one every quarter except for the 0th hour)
= 156 + 72 = 228

Hence all clocks are working fine.
