Oh, and you're right that you need to use the filesystem to get monotonicity across apps if they share timebases. That kinda sucks.

Bear in mind, though, that that's only a problem on systems that are running a time daemon that allows large time deltas. I think xntpd can be configured to avoid those, and the kernel mechanisms for adjtimex do support non-decreasing monotonic clocks.
