Welcome to a less than accurate real time clock being "read" in a way
less than accurate fashion. Or not at all if you're never rebooting. ;)
I'm not sure how you might want to go about making anything close to
"perfect" adjustments, but the command you're probably looking for is
'hwclock'. It can set your system time to "BIOS" time directly, and you
should be able to use it to determine a fairly accurate rate of even
hardware clock drift, and after that's known, to further adjust your
time if needed.
