There is more precision in there, but the output routine won't show it
to you. I think the real issue in Stuart's example is that what's being
shown as .746349 is actually .7463494 or something like that. Doing an
extract(epoch) on the stored values might be instructive.
If you don't want to deal with these sorts of issues then yeah, you want
integer timestamps.
