Same offsets for year 9999 (manually re-tabbed for alignment)

 	# zdump -ic 9998,10001 EST5EDT

 	TZ="EST5EDT"
 	-		-	-05	EST
 	9998-03-08	03	-04	EDT	1
 	9998-11-01	01	-05	EST
 	9999-03-14	03	-04	EDT	1
 	9999-11-07	01	-05	EST
 	10000-03-12	03	-04	EDT	1
 	10000-11-05	01	-05	EST
 	#

(Identical output is generated for America/New_York zone.)

Changes occur only in March and November, not in June, which (for all 
future-from-now times) is UTC-04.
