.Sh DESCRIPTION
|
|
.Nm
|
|
runs a digital clock made of reverse-video blanks on a curses
|
|
compatible VDU screen.
|
|
With an optional numeric argument
|
|
.Ar n
|
|
it stops after
|
|
.Ar n
|
|
seconds (default never).
|
|
The optional
|
|
.Fl s
|
|
flag makes digits scroll as they change.
|
|
The optional
|
|
.Fl 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.

|
|
for more information.
|
|
If this variable is not set, the time zone is determined based on
|
|
.Pa /etc/localtime .
