Jan Wieck had a detailed proposal to make that happen at last developper
meeting, but then ran out of time to implement it for 9.1 it seems. The
idea was basically to have a ticker in core, an SRF that would associate
txid_snapshot with wall clock time. Lots of good things would come from
that.

Of course if you think that's important enough for you to implement it
between now and beta, that would be great :)
