To help narrow the date:  I'm also seeing this problem on a Thinkpad
A22p with -current from ~7pm on Aug 8.  I just recently switched to
-current so did not realize this was a new issue, and was trying to
determine if I had a configuration error of some sort.

In addition, I had one weird instance where the clock did the opposite
and increased the speed by the same ratio.  I haven't been able to
reproduce this yet.  (Maybe starting the system in a lower CPU speed
setting and then stepping up would cause it.  I will test this.)

Let me know if you want me try anything or pass along configuration
information.
