org.apache.drill.exec.store.easy.json.values.UtcDateValueListener

All Implemented Interfaces:

ValueListener

Drill-specific extension to allow dates only, expressed in UTC to be consistent with Mongo timestamps.

Drill dates are in the local time zone, so conversion is needed. Drill dates are stored in ms, which is odd.
