     The strftime function formats the tm time value in <timeptr>
     according to the supplied format argument, and stores the result
     in the buffer <string>. At most, <maxsize> characters are placed
     in the string.
 
     The <format> consists of one or more of the codes; as in printf,
     the formatting codes are preceded by a % sign. Characters that do
     not begin with a % sign are copied unchanged to <string>. The
     LC_TIME category of the current locale affects the output
     formatting of strftime.
 
     The formatting codes for strftime are listed below:
 
     Format     Description
 
     %a         Abbreviated weekday name
     %A         Full weekday name
     %b         Abbreviated month name
     %B         Full month name
     %c         Date and time representation appropriate for the locale
     %d         Day of the month as a decimal number (01-31)
     %H         Hour in 24-hour format (00-23)
     %I         Hour in 12-hour format (01-12)
     %j         Day of the year as a decimal number (001-366)
     %m         Month as a decimal number (01-12)
     %M         Minute as a decimal number (00-59)
     %p         Current locale's AM/PM indicator for a 12-hour clock
     %S         Second as a decimal number (00-59)
     %U         Week of the year as a decimal number; with Sunday
                as the first day of the week (00-51)
     %w         Weekday as a decimal number (0-6; Sunday is 0)
     %W         Week of the year as a decimal number; with Monday
                as the first day of the week (00-51)
     %x         Date representation for current locale
     %X         Time representation for current locale
     %y         Year without the century as a decimal number (00-99)
     %Y         Year with the century as a decimal number
     %z         Time zone name or abbreviation; no characters if time
                zone is unknown
     %%         Percent sign
 
     Return Value
 
     The strftime function returns the number of characters placed in
     <string> if the total number of resulting characters (including
     the terminating null) is not more than <maxsize>.
 
     Otherwise, strftime returns 0, and the contents of the string are
     indeterminate.
