I read the man page for hwclock but was still unable to keep the time 
constant after reboot. Even though during boot up the time would be 
correct and say (localtime) when I startx, the time in KDE would be 
either five or ten hours off.

I was able to get the time set where it would remain 5 hours behind 
eastern time zone.
My fix was to change my time zone to GMT and now everything is the 
same time, MAC OS, YDL and in KDE. It's a sloppy work around but it 
does work.
