Norikra UDF for flexible date formatting.

This UDF works on the following environment:

• Norikra 1.4.0
• Java 8

On JRuby which Norikra runs:

$ gem install norikra-udf-dateformat

For a field timestamp which has the UNIX timestamp in a millisecond range,

SELECT dateformat(timestamp, 'yyyy-MM-dd HH:mm:ss', 'UTC') AS s_date
FROM test_target.win:time_batch(5 min)
