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.
