Basic Sun Light Query - GMT Offset

Recommended Posts

Hi Des,

 

Location is set via city, or longitude/latitude. Daylight Saving not observed automatically. A site may be anywhere on the globe- not just major cities- so a prohibitively large database of daylight saving geographical boundaries would have to be maintained. Also, the period when daylight saving is observed is subject to local laws that periodically change.

 

Adjust the GMT offset to accomodate Daylight Saving. For instance, here in L.A., we are -7 or -8, depending on the time of year.

 

I usually consult this service for site and timedate info: http://www.timeanddate.com/worldclock/usa/los-angeles
