strftime(3)						     Library Functions Manual						       strftime(3)

Name
       strftime - convert time and date to string

Syntax
       #include <time.h>

       int strftime (s, maxsize, format, tm)
       char *s;
       size_t maxsize;
       char *format;
       struct tm *tm;

Description
       The  function  places characters in the array pointed to by s.  No more than maxsize characters are placed into the array.  The string con-
       trols this process.  This string consists of zero or more directives and ordinary characters.  A directive consists of a character followed
       by  a  character that determines the behavior of the directive.	All ordinary characters are copied unchanged into the array, including the
       terminating null character.

       Each directive is replaced by the appropriate characters as shown in the following table. The characters are determined	by  the  program's
       locale category and the values contained in the structure pointed to by tm.

   International Environment
       LC_TIME	      Contains the user's requirements for language, territory, and codeset for the time format.  affects the behavior of the time
		      functions in If is not defined in the current environment, provides the necessary default.

       LANG	      If this environment is set and valid, uses the international language database named in the definition to determine the time
		      formatting rules. If is defined, its definition supercedes the definition of

Return Values
       If  the	total  number  of  resulting characters, including the terminal null character, is not more than maxsize, the function returns the
       total of resultant characters placed into the array pointed to by s, not including the terminating null character.  In all other cases zero
       is returned and the contents of the array are indeterminate.

       As the name is not contained in the tm structure the value returned by %Z is determined by the function, see
