In addition to other's suggestion, I strongly suggest:
a) you run the ntpd service which will sync. the kernel clock to an
external time server (many available on the 'Net)
b) create a script (ntpdate -u <time server>) which will update the
kernel clock at regular interval (depends on your leaning)
then sync your CMOS (hw) clock with the kernel clock
"/sbin/hwclock --localtime --systohc" replace --localtime with --utc if
you want CMOS clock as UTC.
