The <timer> value is usually obtained from a call to time, which returns the number of seconds elapsed since midnight (00:00:00), December 31, 1899, Universal Coordinated Time. The string result produced by ctime contains exactly 26 characters and appears in the following form: Wed Jan 02 02:03:55 1991\n\0 A 24-hour clock is used. All fields have a constant width. The newline character (\n) and the null character (\0) occupy the last two positions of the string. Calls to ctime modify the single statically allocated buffer used by the gmtime and localtime functions. Each call to one of these routines destroys the result of the previous call. The ctime function also shares a static buffer with the asctime function. Thus, a call to ctime destroys the results of any previous call to asctime, gmtime, or localtime. Return Value The ctime function returns a pointer to the character string result. If <timer> represents a date before midnight, December 31, 1899, ctime returns NULL. -♦-
