On Linux/Unix systems: quite easy to do (crontab).

On Windows, you'll have to use some bash-style 
commandline ; using bash given with cygwin (www.cygwin.com)

The best solution imho: install crond using cygwin, and 
create this kind of script in  /home/myuser:

/cygdrive/d/Program\ Files/WinHTTrack/httrack.exe "-*" -
O "/cygdrive/d/My\ Web\ Sites/foo-`date +%m%d%y`"

And put it on a file (for example, named 'httrack-sched') 
in /etc/cron.d/ (here, everyday at 22): ('myscript stands 
for the script above, and ' 'myuser' stands for a regular 
user)
22 0 * * *     myuser     /home/myuser/myscript
