Are you running estd (from pkgsrc)? Or, was the 35:60 from when you  
had booted running from battery maybe?

In any case, you should use an alternate timer if you are using  
speedstep -- TSC is known not to handle changes in CPU speed  
properly. This can be done by, eg:

	# sysctl -w kern.timecounter.hardware=i8254

You probably want to use the ACPI timer for finer granularity, if  
possible.
