The timezone parameter used in this API is the name of the time zone as defined by the IANA timezone Database:

https://www.iana.org/time-zones

These are the same timezone names as used in the Python pytz library:

https://pypi.python.org/pypi/pytz/

Converting from a Microsoft Windows timezone to an IANA timezone can be accomplished using the Noda Time library:

https://github.com/nodatime/nodatime

Not all IANA timezone names are supported by the StarLeaf Cloud. Below is a complete list of valid timezone parameters that are supported:
