My hardware clock keeps going out of sync. I set it to system time a few times, but it keeps going back to the 5hrs ahead state. Is this normal? Could it make trouble? How come my system clock is functioning properly when my hardware clock doesn't?

I do not know if it is normal, or not, because I do not know why the hardware clock should go crazy. If it's a hardware issue, you could use a software workaround until you fix it.

Thehwclock command should do what you need. You can use it in the terminal, as root, in order to set the system clock from the hardware clock, or to set the hardware clock from the system clock (depending on which one is more reliable):

hwclock --hctosys or hwclock --systohc

From the hwclock man page:

   -s, --hctosys
              Set the System Time from the Hardware Clock.

              [...] This  is  a  good  option  to  use  in one of the system startup
              scripts.

       -w, --systohc
              Set the Hardware Clock to the current System Time.
