Mark, could you please look at this?  You changed the code to use
floor instead of rounding via format "%.0f", but floor returns an
Emacs integer which can overflow on 32-bit hosts for large time
values, as happens here.  I think we should use ffloor instead, and if
that produces a decimal point, eliminate it with "%.0f" format.

TIA
