shutdown

I have a Mac OS X 10.5 server, with a RAID set in it, that went down due to a power outage on Thursday, and the machine is not happily booting right now*.

It is possible to find out when the machine went down, while not booted off the internal drive? (I'm booted off an external drive, waiting for the RAID sets to initialize.)

Normally, I'd run last. The man page doesn't indicate that I can run it against a different startup volume. It looks possible to parse /var/log/utmpx, but I don't think it'd be worthwhile to try to do that from scratch for this one-off problem.

* I'm still trying to figure out why it isn't happy, and may ask a follow-up question. Right now I can see that UserNotificationCenter crashed repeatedly early Thursday morning, and that securityd, mdworker, and ARDAgent crash shortly after startup [I think -- I want to verify when the box went up and down]. The login window does not come up right (I think it is crashing or not able to cope with a dead securityd). The box is supposed to be set to go down when the UPS tells it power is out; at the moment, I'm wondering if it went down, and turned back on multiple times! I sure hope not.
