While this is strictly 24 hours and 1 second in conventional units, a digital clock of suitable capability level will most often display the leap second as 23:59:60 and not 24:00:00 before rolling over to 00:00:00 the next day, as though the last "minute" of the day were crammed with 61 seconds and not 60, and similarly the last "hour" 3601 s ...

Bit 53B gives warning that the summer time bit is about to change. It is set for 61 consecutive minutes, starting 1 hour 7 seconds before the change, and ending 7 seconds before the change, 5 seconds before the first changed bit 58B, which is itself transmitted 2 seconds (1.7–1.8 seconds, to be more precise) before the moment of the time change.

Using the definition of kè as 1 ⁄ 100 of a day, each kè is equal to 0.24 hours, 14.4 minutes, or 14 minutes 24 seconds. Every shí contains 8 1 ⁄ 3 kè, with 7 or 8 full kè and partial beginning or ending kè. These fractional kè are multiples of 1 ⁄ 6 kè, or 2 minutes 24 seconds.
