asctime

Defined in header <time.h>
char* asctime( const tm* time_ptr );

Converts given calendar time tm to a textual representation. The resulting string has the following format:

Www Mmm dd hh:mm:ss yyyy

• Www - the day of the week (one of Mon, Tue, Wed, Thu, Fri, Sat, Sun).
• Mmm - the month (one of Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec).
• dd - the day of the month
• hh - hours
• mm - minutes
• ss - seconds
• yyyy - years

The function does not support localization.

Parameters

time_ptr

-

pointer to a tm object specifying the time to print

Return value

pointer to a static null-terminated character string holding the textual representation of date and time. The string may be shared between asctime and ctime, and may be overwritten on each invocation of any of those functions.

Notes

This function returns a pointer to static data and is not thread-safe. POSIX marks this function obsolete and recommends strftime instead.

The behavior is undefined if the output string would be longer than 25 characters, if timeptr->tm_wday or timeptr->tm_mon are not within the expected ranges, or if timeptr->tm_year exceeds INT_MAX-1990.

Some implementations handle timeptr->tm_mday==0 as meaning the last day of the preceding month.
