Egg

This program can help if you looking for a program to measure how much time you spend on jobs, time chess games, or to prevent you freezing soft-drink cans.

Egg can count up and down, is settable by second divisions from 1 second up to 45 days, and while its default window size is compact, it can be varied to whatever size you want (including borderless full screen) to allow you to see the count from across the room.
