Formatting Dates and Times

Formatting Dates and Times

All of these dates can mean the same thing to different people:

92.1.4

4/1/92

1/4/92

All of these can mean the same time to different people:

2:30 PM

14:30

14h30

Dates and times can be easily formatted by using strftime(), which gives a host of options for displaying locale-specific dates and times. The ascftime() and cftime() functions give further options, but should be avoided because they do not conform to ANSI and XPG/4 specifications. The old asctime() and ctime() functions are now obsolete; use strftime() instead. For more information, see the strftime(3C) reference page.
