Hi John, If the time zone is UT + 5 hours 30 minutes the standard meridian indeed is -5.5 * 15 = -82.5 degrees. Succes with the sundial and please let us know how this project is going.

I am designing a monumental sundial for New Delhi India (a new building that will called the "Time Tower"). But I've run into I problem I've never had to deal with before. The problem is that India has a strange Time Zone. Its Time Zone is UT + 5 Hrs. 30 Min. I am using ZW 2000 to design the dial. Here is my question: What number should I enter into Zonwvlak for the Standard Meridian? My thinking goes like this: The sundial will be located at local meridian (longitude) -77.0769 degrees. If it had a normal time zone, the Standard Meridian would be -75 degrees (UT+ 5 hrs.). But since its Time Zone is UT +5:30, then wouldn't its Standard Meridian be -(75 + 7.5) = -82.5 degrees? Is this correct?
