-V, --version
Print version and exit
-t, --time
also display time in the output, default is to display the date
-q, --quiet
Suppress message about date/time and duration parser errors.
-f, --format=STRING
Output format. This can either be a specifier string (similar to strftime()'s FMT) or the name of a calendar.
-i, --input-format=STRING...
Input format, can be used multiple times. Each date/time will be passed to the input format parsers in the order they are given, if a date/time can be read successfully with a given input format specifier string, that value will be used.
-e, --backslash-escapes
Enable interpretation of backslash escapes in the output and input format specifier strings.
-S, --sed-mode
Copy parts from the input before and after a matching date/time. Note that all occurrences of date/times within a line will be processed.
-l, --locale
Make internal strptime(3) and strftime(3) behave in a locale dependent way, default is to pretend LC_ALL=C is in place.

  %c  The count of the weekday within the month (range 00 to 05)
  %C  The count of the weekday within the year (range 00 to 53)
  %d  The day of the month, 2 digits (range 00 to 31)
  %D  The day of the year, 3 digits (range 000 to 366)
  %F  Equivalent to %Y-%m-%d (ymd's canonical format)
  %g  ISO week date year without the century (range 00 to 99)
  %G  ISO week date year including the century
  %j  Equivalent to %D
  %m  The month in the current calendar (range 00 to 19)

  %y  The year without a century (range 00 to 99)
  %Y  The year including the century
  %_y The year shortened to a single digit
  %Z  The zone offset in hours and minutes (HH:MM) with
      a preceding sign (+ for offsets east of UTC, - for offsets
      west of UTC)
  %Od The day as roman numerals
  %Om The month as roman numerals
  %Oy The two digit year as roman numerals
  %OY The year including the century as roman numerals
  %rs In time systems whose Epoch is different from the unix Epoch, this

  ymcw    %Y-%m-%c-%w
  ywd     %rY-W%V-%u
  bizda   %Y-%m-%db
  lilian     n/a
  ldn        n/a
  julian     n/a
  jdn        n/a
These designators can be used as output format string, moreover, @code{lilian}/@code{ldn} and @code{julian}/@code{jdn} can also be used as input format string.

  $ strptime -i '%a, %b-%d/%Y' 'Mon, May-01/2000'
  2000-05-01
  $
  $ strptime -i '%a, %b-%d/%Y' <<EOF
