Windows Update and Error 0x8DDD0009

I was encountering a Windows Update error 0x8DDD0009 on a Windows 2000 SP4 system. I tried a number of things like stopping and restarting the Windows Update Auto Update service (wuauserv) rebooting, unregistering Windows Update-related components, etc. and nothing worked. Then I noticed the time on the system was off by about 22 minutes. I changed the time to be correct, and Windows Update magically started working again.

FWIW, 0x8DDD0009 can be interpreted to mean a lot of things...
