How to Coordinate Across Time Zones
GMT (Greenwich Mean Time)
GMT is the time at the Royal Observatory in Greenwich, London. It serves as the reference point for all world time zone calculations.
UTC (Coordinated Universal Time)
UTC is the primary time standard. All time zones are expressed as positive or negative offsets from UTC (e.g., UTC-5 for New York).
EST, PST, CST (US Time Zones)
Eastern (EST-5), Pacific (PST-8), and Central (CST-6) Standard Time. During daylight saving, these become EDT (UTC-4), PDT (UTC-7), and CDT (UTC-5).
DST (Daylight Saving Time)
Many countries shift clocks forward by 1 hour during summer months to extend evening daylight. DST typically starts in spring and ends in autumn.
