status.i4.v = year_to_dst_dates_c(year.i4.v, first_dst_date.u4.r,
					  first_dst_tm.s.r, last_dst_date.u4.r,

	This routine returns the beginning and ending DST dates
	for a given year.

	year		requested year
			(If a value of 0 is passed for this argument,
			 the current year is used.)
	first_dst_date	returned first DST date in clinks
	first_dst_tm	returned first DST date structure
			(structure of type struct tm)
	last_dst_date	returned last DST date in clinks
	last_dst_tm	returned last DST date structure
			(structure of type struct tm)

	This function returns ACNET status values as follows:

	OK			success
