It is possible if you have a GNU date installed.
Ex:
date +%s --date="Wed Oct 15 04:58:06 2008"
gives you:
1224043086

you can install GNU date. Is that an option for you?
Also you can do it with Perl. Do you want Perl script ?

If you want to do it in pure bash, it's going to be a pretty tedious script.  GNU date really is your best/easiest option.

Actually, you may be able to use the BSD date command like:


date -j -f date -j -f "%a %b %d %T %Y" "Wed Oct 15 04:58:06 2008" +"%s"
