How to Convert Time Between World Time Zones
Converting time between locations requires knowing the active UTC offset for each location and accounting for seasonal daylight saving adjustments.
Whether checking what time a webinar takes place in another country, scheduling an international phone call, or verifying flight schedules, an accurate time converter eliminates manual mental calculations.
Time Clock 24 uses the authoritative IANA time zone database natively in your browser to automatically resolve fractional offsets (such as UTC+5:30 in India or UTC+5:45 in Nepal) and handles DST shifts without error.

How Daylight Saving Affects Time Conversions
Daylight saving transitions do not occur simultaneously worldwide. For example, North America typically begins daylight saving time in the second week of March, while Europe transitions in the final week of March.
DST Transition Gap Notice
Time Clock 24 highlights whenever an entered time falls within a spring-forward transition gap or repeated autumn hour so your schedule remains accurate.
Frequently Asked Questions
What time is 10 AM EST in GMT?
10:00 AM Eastern Standard Time (EST, UTC−5) corresponds to 3:00 PM Greenwich Mean Time (GMT, UTC+0) — a 5-hour difference.
What time is 3 PM London time in New York?
When London is observing GMT (UTC+0), 3:00 PM London time is 10:00 AM in New York (EST, UTC−5). When London observes BST (UTC+1) and New York observes EDT (UTC−4), the 5-hour difference remains standard.
How do you convert UTC to local time?
To convert UTC to local time, add your time zone offset if you are east of the Prime Meridian (positive offset like UTC+3) or subtract your offset if you are west (negative offset like UTC−5).
Does daylight saving time affect time zone conversion?
Yes. Because countries switch between standard time and daylight saving time on different dates, the hour difference between two cities can temporarily change during spring and autumn transitions.
