Issue in ner_duckling

I am trying to use ner_duckling in rasa_nlu and unable to change time zone. By-default, it is giving output on the basis of UTC-timezone while I need output on the basis of IST timezone. Please let me know how can i change it from UTC to IST.

I am using ner_duckling in pipeline as:

- name: "ner_duckling"
  dimensions: ["time"]
  timezone: "Asia/India"
  locale: "en_GB"

I answered this somewhere else as well but the timezone here used by duckling is

Asia/Mumbai

Please use the ner duckling over http
