This issue was originally posted for PySAM at NatLabRockies/pysam#54:

The PVWatts7 module includes a time zone output. However, this output does not seem to exist for any of the other modules, including the windpower modules and concentrating solar power modules.

Especially when working with resources across multiple time zones, it would be nice to have this output so that timeseries outputs can be easily converted to a single time zone.
