    Starts a countdown to TIME. Example values for TIME:
    10, '1h 5m 30s', '12:00', '2020-01-01', '2020-01-01 14:00 UTC'.

    If TIME is not given, termdown will operate in stopwatch mode
    and count forward.

    Hotkeys:
    	E	Show end time (countdown mode only)
    	L	Lap (stopwatch mode only)
    	R	Reset
    	SPACE	Pause (will delay absolute TIME)
    	+	Plus (will add 10 seconds)
    	-	Minus (will subtract 10 seconds)
    	Q	Quit

positional arguments:
  timespec              TIME to countdown to. Example values: 10, '1h 5m 30s', '12:00', '2020-01-01', '2020-01-01 14:00 UTC'. If not given, operates in stopwatch mode.

options:
  -h, --help            show this help message and exit
  -a, --alt-format      Use colon-separated time format
  -b, --blink           Flash terminal at end of countdown
  -B, --no-bell         Don't ring terminal bell at end of countdown
  -c, --critical N      Draw final N seconds in red and announce them individually with --voice or --exec-cmd (defaults to 3)
  -e, --end             Display target datetime of unpaused countdown
  -f, --font FONT       Choose from https://www.ascii-art.site/FontList.html or provide a full path to an OTF/TTF file
  --font-charset CHARSET
                        Provide a string of characters of increasing visual density (e.g. " .oO#@") to render OTF/TTF pixels
  --font-size N         Set font size when using OTF/TTF
  -p, --voice-prefix TEXT
                        Add TEXT to the beginning of --voice and --exec annunciations (except per-second ones)
  -q, --quit-after N    Quit N seconds after countdown (use with -b or -t) or terminate stopwatch after N seconds
  -s, --no-seconds      Don't show seconds (except for last minute of countdown and first minute of stopwatch)
  -t, --text TEXT       Text to display at end of countdown
  -T, --title TITLE     Text to display on top of countdown/stopwatch
  -W, --no-window-title
                        Don't update terminal title with remaining/elapsed time
  -v, --voice VOICE     Spoken countdown (at fixed intervals with per-second annunciations starting at --critical; requires `espeak` on Linux or `say` on macOS; choose VOICE from `say -v '?'` or `espeak --voices`)
  -o, --outfile PATH    File to write current remaining/elapsed time to
  --exec-cmd CMD        Runs CMD every second. '{0}' and '{1}' in CMD will be replaced with the remaining/elapsed number of seconds and a more sparse annunciation as in --voice, respectively. For example, to get a callout at five seconds only, use: --exec-cmd "if [ '{0}' == '5' ]; then say -v Alex {1}; fi"
  --no-art              Don't use ASCII art for display
  --no-text-magic       Don't try to replace non-ASCII characters (use with -t)
