Hmm, right, that would be pretty useful.

Well, you should probably use the AppDefaults config mechanism in the
config file for that (cmdline options are eeeevil).
Just add a setting called e.g. TweakTime, and maybe use the following syntax:
"TweakTime" = "=1999:11:03:..."
"TweakTime" = "-1:02:01:...."
"TweakTime" = "+......."
You should probably use a "standard" unix time format, not the mess I created
here ;-)
Oh, and if you do implement config flag reading for GetSystemTime and
GetLocalTime, then make *absolutely* sure that this happens in a very fast
way, i.e. completely cached.
And if you have problems calculating the different '=','-','+' modes
(slower calculation), then make sure that it's still as fast as possible
(i.e. split it).

See loader/loadorder.c/get_app_load_order() for an AppDefaults example.

Thanks for doing this ! ;-)
