timestampFormat
The format the timestamp field in your JSON object is specified. This value should be one of EPOCHMILLI (for Unix epoch timestamps with second/millisecond level precision) or ISO_8601 (following ISO_8601 format with second/millisecond level precision, with an optional offset of Z or in the format HH:MM or HHMM.). E.g. if your object type is MyType and source JSON is {"generatedAt": {"timestamp": "2001-07-04T12:08:56.235-0700"}}, then TimestampFormat should be "ISO_8601".
