I just had an extended power outage and all my servers were rebooted. When checking the boot time from a terminal using /usr/bin/last | grep boot, I noticed a discrepancy in the times displayed. My servers are all set to local time (PDT) not UTC.
On f13 and f14 servers, the time shown by last was the correct 13:02. On f15 servers the time was shown as 06:02. The only thing I can figure is newer version of last assumes the times it reads from wtmp are UTC, and last then applied the GMT-7 offset again, giving me the wrong time.
Anyone else ever run across this?
