Converts a date and time structure to string form

#include <time.h>
char *asctime ( struct tm *systime  );

The single argument of the asctime( ) function is a pointer to a structure of type struct tm, in which a date and time is represented by elements for the year, month, day, hour, and so on. The structure is described under mktime( ) in this chapter. The asctime( ) function returns a pointer to a string of 26 bytes containing the date and time in a timestamp format:

"Wed Apr 13 07:23:20 2005\n"

The day of the week and the month are abbreviated with the first three letters of their English names, with no period. If the day of the month is a single digit, an additional space fills the place of its tens digit. If the hour is less than ten, it is represented with a leading zero.

Example

time_t now;
time( &now );                 /* Get the time (seconds since 1/1/70) */
printf( "Date: %.24s GMT\n", asctime( gmtime( &now ) ));

Typical output:

Date: Sun Aug 28 14:22:05 2005 GMT
