Usage: date [-h] [-s EPOCH] [-d @EPOCH] [+FORMAT]
  -h:  shows this help message
  -s:  set system time described by EPOCH (POSIX time format)
  -d:  display time described by EPOCH (POSIX time format)
  FORMAT: string with POSIX date formatting characters
NOTE: FORMAT string not supported by options: '-s', '-d'

Printing accepts FORMAT string that describes how or what part of date should be printed. Available formats are listed further in this document. Format string should start with + sign.
