Hardware Clock Sync Failure

A normal day. I booted the office computer. The computer hung for about a minute and a half when the system clock is synced to the hardware clock.

A few more reboots with the same result.

I enabled hwclock --debug and rebooted. The output spew included Waiting for clock tick and synchronization failed.

I stared for several moments.

I fetched a new CMOS battery.

Problem solved.

I seemed to recall changing the battery not long ago. Some digging revealed less than a year ago.

Bad battery? Bad luck?
