DESCRIPTION
This module provides routines to format dates. They correspond to the libc routines. &strftime() supports a pretty good set of coversions
-- more than most C libraries.
strftime supports a pretty good set of conversions.
The POSIX module has very similar functionality. You should consider using it instead if you do not have allergic reactions to system
libraries.
