Looks fine in Gmail - kinda cool cursive script that I'm guessing is
right to left...

I wondered myself about that - I did some googling and all I came up
with was this post that says it's
seconds since boot to 6 decimal places but doesn't have any links to
backing material.  And, his own message seems to indicate there's more
to it than that.  If anybody has more info I'd be interested too.
