What are the advantages of using a 24-hour clock?
All of the above
A 24-hour clock does not require suffixes like A.M. or P.M. This helps prevent confusion.
The time in this clock never repeats for 24 hours as it starts from 0000 hours and ends at 2359 hours.
When travelling from one time zone to the other, there is a confusion whether its the morning or the evening. This confusion can be avoided with a 24-hour clock.
