GRDC(6) FreeBSD Games Manual GRDC(6)
NAME grdc - grand digital clock (curses)
SYNOPSIS grdc [-st] [n]
DESCRIPTION grdc runs a digital clock made of reverse-video blanks on a curses compatible VDU screen. With an optional numeric argument n it stops after n seconds (default never). The optional -s flag makes digits scroll as they change. The optional -t flag tells grdc to output the time in a 12-hour format. In this curses mode implementation, the scrolling option has trouble keeping up.
ENVIRONMENT TZ The time zone to use for displaying the time. It is normally specified as a pathname relative to /usr/share/zoneinfo, though see tzset(3) for more information. If this variable is not set, the time zone is determined based on /etc/localtime.
AUTHORS Amos Shapir, modified for curses by John Lupien.
