[Radiance-general]radiance daylight study

[steve michel]

As I replied to Greg, I set the sketchup location and time to what was required for the simulation. And the north direction as well.
Somehow the export creates a five hour difference. 

Is there a time-zone setting in the SU2RAD ruby script?

regards
Steve
