       tty-clock - a terminal digital clock


       tty-clock [-iuvsScbtrahDBxn] [-C [0-7]] [-f format] [-d delay] [-a nsdelay] [-T tty]


       tty-clock displays a simple digital clock on the terminal. Invoked without options it will
       display the clock on the upper left corner of the screen on the terminal it  was  executed


       tty-clock  accepts  a number of runtime keyboard commands, upper and lower case characters
       are treated identically.

              vi-style movement commands to set the  position  of  the  displayed  clock.   These
              commands have no effect when the centered option is set.

       [0-7]  Select a different color for displaying the clock.

       B      Toggles bewteen bold and normal colors.

       X      Toggles displaying a box around the clock. This option is disabled by default.

       C      Toggle  the  clock's  position  to  centered.   When  set the movement commands are

       R      Set the clock to rebound along the edges of the terminal.

       S      Display seconds.

       T      Switch time output to the 12-hour format.

       Q      Quit.


       -s     Show seconds.

       -S     Screensaver mode. tty-clock terminates when any key is pressed.

       -x     Show box.

       -c     Set the clock at the center of the terminal.

       -C [0-7]
              Set the clock color.

       -b     Use bold colors.

       -t     Set the hour in 12h format.

       -u     Use UTC time.

       -T tty Display the clock on the given tty. tty must be a valid character device  to  which
              the user has rw access permissions.  (See EXAMPLES)

       -r     Do rebound the clock.

       -f format
              Set the date format as described in strftime(3).

       -n     Do not quit the program when the Q key is pressed (or when any key is pressed while
              in Screensaver mode). A signal must be sent to tty-clock in order to terminate  its
              execution. (See EXAMPLES)

       -v     Show tty-clock version.

       -i     Show some info about tty-clock.

       -h     Show usage information.

       -D     Hide the date.

       -B     Enable blinking colon.

       -d delay
              Set the delay (in seconds) between two redraws of the clock. Default 1s.

       -a nsdelay
              Additional delay (in nanoseconds) between two redraws of the clock. Default 0ns.


       To  invoke  tty-clock  in  screensaver  mode with the clock display set to rebound and the
       update delay set to 1/10th of a second (10 FPS):

              $ tty-clock -Sra 100000000 -d 0

       The following example arranges for tty-clock to be displayed indefinitely on  one  of  the
       Virtual Terminals on a Linux system at boot time using an inittab(5) entry:

              # /etc/inittab:
              9:2345:respawn:/usr/bin/tty-clock -c -n -T /dev/tty9
