Index the dates and times as integer timestamps. Then you can easily search in an index for dates between other timestamps. You can also index the time part of the timestamp separately as another integer, allowing you to query for specific times between given dates.
Example:
The date and time to store is “2012-02-05 8:15 AM”
So in your index, store “timestamp=1328447700” and “time=815”
Now you want to query the index for all events between 2012-02-01 and 2012-02-10 that occurred from 8:00 am to 9:00 am. You do that by querying the index for
“timestamp>=1328072400 and timestamp<=1328936399 and time>=800 and time<=900”
The exact syntax for doing this depends on how you are connecting to Neo4j (REST or embedded) and which programming language you are using. But the idea is the same in any case.
