How does the UTC time work?
A- If your target date signifies an event at a certain location, you should append your UTC (Coordinated Universal Time) to your date. UTC is also referred to as GMT (Greenwich Mean Time). See Wikipedia article on UTC. The UTC time is never adjusted so if you are in a Daylight savings zone, time changes could complicate matters. For example The US northeast is 5 hours behind UTC in standard time and 4 hours behind UTC in daylight savings time. So if you are hosting an event in northeastern United States on July 11, 2015 at 4 PM, you would specify “07/11/2015 4:00 PM UTC-0400”, as that region is generally under daylight savings during that time. Alternatively you could specify “07/11/2015 4:00 PM EDT”. In this case EDT is used to indicate Eastern Daylight Time, rather than EST (Eastern Standard Time).
