12-Hour and 24-Hour Formats

Let's discuss one more moment with times - 12 and 24-hour formats. Many countries use the 24-hour format in documents, but 12-hour format in daily communication. At the same time, many countries use the 12-hour time format only. So, we need to learn how to deal with and be able to format such times.

There are several more format codes to deal with this issue.

Format codeMeaningExample
%HHour (24-hour clock) as a zero-padded decimal number00, 01, ..., 22, 23
%IHour (12-hour clock) as a zero-padded decimal number01, 02, ..., 11, 12
%pLocale’s equivalent of either AM or PMAM, PM

Tarefa

Given datetime object dt with date 28 June 2002 and time 14:58:41. Extract the time into two formats: 14:58 and 02:58 PM.
