I am getting following error while fetching data through API. There are two parameters which get passed in the call. 1) Sequence Number (I am sure that this is working fine) 2) Time Zone - This one I am not able to crack the format/value whihc should be given.

What value should I pass in time_zone to get a 200 Ok response.
