PC timer for online tests, howto

I needed a timer to take online tests with (on an IBM PC).

And I found PC Timer. It seems ideal for this purpose:

In order to alert me when a timed test is nearly over, I configured it to run this simple batch file:

@echo off
mode con: cols=100 lines=8
color 4e
echo .
echo .
echo "Time's up"
echo .
echo .
pause

Simple!

Presumably, it will be useful in timing other things, as well.

Beyond the timer, it also has two alarms (for moments, rather than durations, as of version 4.0).
