	* src/fn-date.c (gnumeric_year_month_day, gnumeric_now,
	gnumeric_today,gnumeric_date):
	* src/workbook.c (insert_current_date_cmd):
	* src/number-match.c (compute_value): Changed to use the glib
	GDate type instead of the lib_date functions. Fixed off by-one
	error for some date functions (e.g. =today ()) was one day to
	early).

	* src/utils.c, src/utils.h (g_date_serilal, g_date_serial_new):
	New functions for handling the gnumeric serial of a date.
