With an optional numeric argument -.I n +runs a digital clock made of reverse-video blanks on a terminal screen. +If the terminal supports color, the clock is drawn in red. +You can make the clock stop, pause or resume by pressing a ``q'', +``s'' or space, respectively. +.SH OPTIONS +.TP +.B \-d +use terminal's default colors for the background. +.TP +.B \-n +redirects input to /dev/null, making it ignore the stop/pause commands. +You can still stop it by pressing the interrupt key. +.TP +.B \-s +makes digits scroll as they change. +When running on a fast display, the program breaks up the scrolling into +subsecond repaints, making the operation appear smooth. +.TP +.B \-t \fIhh:mm:ss\fP +specify starting time (default is ``now''). +.PP +With an optional numeric argument +.I num it stops after -.I n -seconds (default never). -The optional -.B -s -flag makes digits scroll as they change. In some curses mode implementations, -the scrolling option has trouble keeping up. +.I num +seconds. +Normally it runs "forever" (counting down from 2 billion seconds). .SH AUTHOR Amos Shapir, modified for curses by John Lupien. +.br +Improvements for ncurses by Thomas Dickey.
