Class UtcDateValueListener

java.lang.Object

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

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

All Implemented Interfaces:

ValueListener

public class UtcDateValueListener
extends ScalarListener

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.
