| Description: |
This is a simple Tk script to countdown the days, hours, minutes, seconds, and milliseconds until a particular event. It requires Tk, DateTime, and Time::HiRes.
The script creates a window in the upper-right corner of the screen and displays the countdown information there.
Have fun.
Update: Upper-left |
