asctime

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

Converts given calendar time Template:cpp 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 Template:cpp 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 Template:cpp, 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 Template:cpp 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 Template:cpp.

Some implementations handle Template:cpp as meaning the last day of the preceding month.
