Good point.

One of my concerns is the procedural mess of setting system time, and the
combination of Linux + borrowed computers could create a particularly
troublesome version of that procedure.

Linux runs using GMT throught with knowing conversions, Windows seems to
have multiple points of view on this. But at the bottom, Windows stores
time between boots in the nvram in local time. Linux does it in either
local time or GMT.

This means that when I boot Linux on a box that ran windows previously I
often come up with the right minute but the hours are off by 7 or 8
(depending on whether daylinght time is in effect.) And when setting the
time to be the right time it's easy, with that kind of time offset to get
the date part messed up.
