Running "hwclock --localtime --systohc" will set it to local time. With both Windows and Linux on the same machine, you probably should have the hardware clock set to local time. Because the system time is written back to the hardware clock when FC shuts down, you can run into problem if it is not set correctly. If Linux expects UTC and Windows expects local time, both end up doing large corrections when they boot. You can end up with running corrections that are based on an incorrect drift rate because you are trying to adjust to the time zone difference every time you change the OS. You also run into this problem when you change the hardware clock from local time to UTC on a running system.
