17:00 EST to GMT

22:00 GMT

17:00 Eastern Standard Time equals 22:00 Greenwich Mean Time.

These are standard-time offsets, which never change. What changes is which one a place observes: New York is on EST in winter but EDT (an hour later) during daylight saving, and the UK is on GMT in winter and BST in summer. If you mean "the time in New York right now", use the full converter — it reads live offsets.

How the conversion works

This one is a formula rather than a single multiplier:

GMT = EST + 5 hours → 22:00 GMT

Going the other way: 22:00 GMT to EST.
