strftime #include <ctime> size_t strftime( char *str, size_t maxsize, const char *fmt, struct tm *time ); The function strftime() formats date and time information from time to a format specified by fmt, then stores the result in str (up to maxsize characters). Certain codes may be used in fmt to specify different types of time: Code Meaning %a abbreviated weekday name (e.g. Fri) %A full weekday name (e.g. Friday) %b abbreviated month name (e.g. Oct) %B full month name (e.g. October) %c the standard date and time string %d day of the month, as a number (01-31) with a leading zero %-d day of the month, as a number (1-31) without a leading zero %H hour, 24 hour format (0-23) %I hour, 12 hour format (1-12) %j day of the year, as a number (1-366) %m month as a number (1-12). %M minute as a number (0-59) %p locale's equivalent of AM or PM %S second as a number (0-59) %U week of the year, (0-53), where week 1 has the first Sunday %w weekday as a decimal (0-6), where Sunday is 0 %W week of the year, (0-53), where week 1 has the first Monday %x standard date string %X standard time string %y year in decimal, without the century (0-99) %Y year in decimal, with the century %Z time zone name %% a percent sign Some versions of Microsoft Visual C++ may use values that range from 0-11 to describe %m (month as a number).
