--type=<elapsed-line|elapsed-total|absolute>        [default: elapsed-line]
-t <elapsed-line|elapsed-total|absolute>

  Type of timestamp to display.
    elapsed-line: Number of seconds that displayed line was the last line.
    elapsed-total: Number of seconds since the start of the process.
    absolute: An absolute timestamp in UTC.

--format="format"                                   [default: "H:i:s.u O"]
-f "format"

  Format the absolute timestamp, using PHP date format strings. If the type
  is elapsed-line or elapsed-total, this option is ignored.

--ignore-blank                                      [default: false]
--quiet
-q
-i

  Do not prepend a timestamp to blank lines; just pass them through. When
  this option is active, blank lines will not trigger an update of elapsed
  time. Therefore, if a lot of blank lines appear, the prior timestamp will
  display the total time between that line and the next non-blank line
  (if the type is elapsed-time was selected).

--real-time=<number|false>                          [default: 500]
-r                                                  [non-tty default: false]

  Time increment to use when updating timestamp for the current line, in
  milliseconds. Pass `false` to this option to disable realtime entirely,
  if you need an extra performance boost or you find it distracting. When
  realtime is disabled, the log will always appear one line "behind" the
  original piped output, since it can't display the line until it's
  finished timing it.

--high=seconds
-h seconds

  High threshold. If the elapsed time for a line is equal to or higher than
  this value in seconds, then the timestamp will be colored bright red.
  This works for all timestamp types, including elapsed-total and absolute,
  where the elapsed line time is not actually displayed.

--medium=seconds
-m seconds

  Medium threshold. Works just like the high threshold described above, but
  colors the timestamp bright yellow instead. Can be used in conjunction
  with a high threshold for three levels.
