Yeah, I was looking at that --- I think most if not all of the existing
JROUND calls ought to go away.  Will try to work up a full patch over
the weekend.

I think the solution is that timestamp_out needs to decide how many
fractional digits it wants to display, and then round off the input
accordingly, *before* it breaks the input down into y/m/d/h/m/s fields.
This "60.00" business is happening because the rounding is done only on
the seconds-and-fractional-seconds field.
