From what I've read online, it's a creeping system clock issue in the Linux kernel (the clock gains a minute every 2 or 3 hours, it gains faster if there's more network usage, ntpd cannot compete with that rate of clock skewing). We're going to try using noapic and other parameters.
You can also try running Dan Bernstein's clockspeed:
http://cr.yp.to/clockspeed.htmlusing this helper script:
http://foo42.de/devel/sysutils/clockspeed-conf/WARNING: DJB's software is tersely written and really intended for people who actually know what they are doing.
FWIW, I have not seen this issue at all with the clocks under my control (mostly SLES 9), which have clock drift that varies per machine. With clockspeed, however, I'm usually within a couple of 100ths of a second each time the script checks/adjusts it. YMMV
