       %S     second (00..60)

       %t     a tab

       %T     time; same as %H:%M:%S

       %u     day of week (1..7); 1 is Monday

       %U     week number of year, with Sunday as first day of week (00..53)

       %V     ISO week number, with Monday as first day of week (01..53)

       %w     day of week (0..6); 0 is Sunday

       %W     week number of year, with Monday as first day of week (00..53)

       %x     locale's date representation (e.g., 12/31/99)

       %z     +hhmm numeric timezone (e.g., -0400)

       %::z   +hh:mm:ss numeric time zone (e.g., -04:00:00)

       %:::z  numeric  time  zone  with  :  to necessary precision (e.g., -04,
              +05:30)

       %Z     alphabetic time zone abbreviation (e.g., EDT)

       By default, date  pads  numeric  fields  with  zeroes.   The  following
       optional flags may follow `%':

              - (hyphen) do not pad the field _ (underscore) pad with spaces 0
              (zero) pad with zeros ^ use upper case if possible #  use  oppo-
              site case if possible

       After  any  flags  comes  an optional field width, as a decimal number;
       then an optional modifier, which is either E to use the locale's alter-
       nate  representations  if available, or O to use the locale's alternate
       numeric symbols if available.
