python - Cross-tabulate timestamp for two tables in ArcGIS -

-

I am trying to solve a problem in ArcGIS 10.2 and I would like to complete either Python or here The need to use a SQL statement is to work. I have three datasets:

- A polygon grid with a unique ID - A point feature represents class (A) GPS data with a time stamp and a GPS unit-A's ID number Point feature is collected in every 3 seconds (B) represents a specific event with a timestamp and ID

What is the grid feature table showing what I want to show The old GPS ID (A) was there with 30 seconds of an event (B) which was in the same grid

There can be several events in each grid, so in 30 seconds of each event of that grid A closer unique GPS ID will be required. Can anyone point help in the right direction? I only have basic Python and SQL experience.
