Time formatting subroutines

Programs that need to format time into wide character code strings can use the wcsftime subroutine. Programs that need to convert multibyte strings into an internal time format can use the strptime subroutine.

In addition to the strftime subroutine defined in the C programming language standard, X/Open Portability Guide Issue 4 defines the following time formatting subroutines:

wcsftime

Formats time into wide character code strings

strptime

Converts a multibyte string into an internal time format
