NAME
grdc —
grand digital clock (curses)
SYNOPSIS
grdc |
[-st] [n] |
grdc |
-c 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 clock can act as a
countdown timer with the -c flag,
n specifies the number of seconds to time for. 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.
NOTES
In countdown timer mode, the specifying of
-n > 360000 seconds (100 hours) will lead to the
counter displaying incorrect remaining time, however it will time correctly,
and display correctly when the remaining time becomes less than 100
hours.
