Ugh. If you go down that road, why write human-readable contents at
all? You may as well just use a binary format. But that's a very
slippery slope and you won't like to be in the bottom -- I don't see
what that gains you. It's not like it's a lot of work to parse a
timestamp in a non-internationalized well-defined human-readable format.
