The elapsed time reported by 'time' should be accurate. system and user
time may not be entirely correct, as the kernel doesn't really
understand that its not running the whole time. 

hwclock won't work as the unprivileged guest isn't authorized to read
directly from the hardware clock. 'date' should work fine.
