misc/delay 1.6p0 OpenBSD

Delay is a program that counts down the number of seconds specified on its command line. In this way, it's sort of like the standard sleep(1) command, except for the fact that it provides feedback of the time remaining.

You can also 'delay' until a given time specification. Here some usage example:

delay 1d 2:03:04.5 delay 1d 2h 3m 4.5s delay 93785.5 delay until 4 pm -- cdplay delay until noon tomorrow delay until midnight 13 september 2000 delay until now + 5 minutes delay 15s -- top

It allows for short, long, and customized messages for the display of the time remaining.
