Here's a puzzle. I record host uptime once per day; it gives me an idea
how reliable things are. I expect the uptime report to increase by 24
hours each time I run uptime(1). Apparently not...

19970601 000007 12:00am up 76 days, 13:49, 35 users, load average: 1.09, 0.28, 0
.08
19970701 000003 12:00am up 106 days, 13:55, 39 users, load average: 0.00, 0.01, 
0.00
19970801 000011 12:00am up 137 days, 14:02, 35 users, load average: 1.63, 0.39, 
0.12
19970901 000004 12:00am up 168 days, 14:09, 33 users, load average: 0.46, 0.10, 
0.03

Over the course of 3 months uptime has somehow recorded 3 months and 20
minutes' extra uptime. Could this be due to a fast hardware clock, which is
counting the clock ticks, while the Unix system clock is kept in sync
by NTP?
