How to determine distance and association between two point layers in space AND time?

Discussion created by audsd on Jul 24, 2012
I have very large fine-scale temporal telemetry collar datasets that I wish to compare in space and time. I specifically want to determine a) if the animals are occurring at the same space AND same time (in other words, associating) b) if so, what the distance between these associative points is. I know that there is a Intersect Point Tool in Hawth Tool's Analysis Tools, but that is for intersecting a point and raster file. Is there anything similar for two point layers?
I have looked at the NEAR function in ARC Info, but I do not have access to it. I am working with ARC MAP 9.3. Is there any similar equivalent for ARC MAP?
Any other suggestions would be really appreciated.
