it means either earliest available date or latest available date depending on the placement. so if you see NULL, 1942-10-01 it means that the item is available from the start of the next limiting factor until October 1, 1942.
if you see 1942-10-01, NULL, it means that the item is first available October 1, 1942 until the next limiting factor.
lastly, NULL,NULL means that the item is always available within the context of the next limiting factor.


the "next limiting factor" could be a flotilla or a base or a boat, etc.
for example, you could see an Equipment definition of NULL, NULL which means that it is always available but the boat it is assigned to may have other date limitations. does that make sense?
