EST = Eastern STANDARD Time, ie. Zone time for 75 West, 5 hours west of Greenwich. EDT = Eastern Daylight (savings) Time, our Summer time. Our clocks "Spring" forward in March, and "Fall" back in October, so during the summer they're only 4 hours off of GMT/UTC. Any help? -- Bill -----Original Message----- From: Navigation Mailing List [mailto:NAVIGATION-L@LISTSERV.WEBKAHUNA.COM] On Behalf Of Jared Sherman Sent: Tuesday, November 09, 2004 3:47 PM To: NAVIGATION-L@LISTSERV.WEBKAHUNA.COM Subject: What time is it? No, really. I'm having a moment of confusion over this. Nov. 09, 20:42:00 UTC is the same as Nov. 09, 03:42:00 PM EST according to USNO.NAVY.MIL, and they should know. But I thought there was no daylight savings time correction to UTC, and "EST" is "Eastern Saving Time" (clocks moved an hour behind real time) in the eastern US now. Or, is this another instance of a difference between GMT and UTC, where UTC changes but GMT doesn't? Can someone unconfuse me on how US times, UTC, and GMT all do or don't vary with Daylight Slavings Time?
