Class UtcTimestampValueListener

java.lang.Object

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

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

All Implemented Interfaces:

ValueListener

public class UtcTimestampValueListener
extends ScalarListener

Per the V1 docs: In Strict mode, <date> is an ISO-8601 date format with a mandatory time zone field following the template YYYY-MM-DDTHH:mm:ss.mmm<+/-Offset>.

In Shell mode, <date> is the JSON representation of a 64-bit signed integer giving the number of milliseconds since epoch UTC.

Drill dates are in the local time zone, so conversion is needed.
