rem Test Timing
rem You might need to set this in later versions and also use !time setlocal enabledelayedexpansion
set start_time=%time%
echo start_time is %start_time%
pause
rem Replace above 'pause' with activity to be timed (approx).
set end_time=%time%
rem Now calculate time difference
echo started %start_time%
echo ended %end_time%
rem To get a substring, do this:
rem %variable:~num_chars_to_skip,num_chars_to_keep%
rem Here we also prepend "1" to 2-digits and then subtract 100
rem to avoid numbers like "02"
rem which can cause errors in the windows batch interpreter.

Lots of "pause"s to check how it's going.
You can take them out.
Better versions welcome, too.
