	* R/dates.R:

2001-09-18  Kurt Hornik  <Kurt.Hornik@ci.tuwien.ac.at>

	* DESCRIPTION (Version): New version is 2.2-18.

	* R/chron.R (chron): the default for the argument `out.format' was
	wrong if the argument `format' was a function or R symbol (in
	these cases `out.format' now is not set and we stop).  As the
	current code does not always preserve format slots, we need to
	make a NULL format correspond to the default.
	* R/dates.R (convert.dates): now correctly handles formats given
	as R symbols.
	* R/times.R (convert.times): now correctly handles formats given
	as R symbols.
	* R/utils.R (month.day.year): now coerces its argument to be
	integer since the algorithm requires integer arithmetic.
	All fixes by David James.

	* R/times.R: format.times() needs to round its calculation of
	sec (suggested by BDR).
