To make the conversion, follow these steps: For example, if daylight saving time in your time zone is one hour ahead of standard time, add one hour to the offset-adjusted time.Ĭonvert the 24-hour time format to 12-hour time format if your local time uses the 12-hour format. Coordinated Universal Time (UTC) +0000 UTC UTC/GMT is 21:41 on Saturday, AugDST Time Zone Map Daylight Saving Time This location does not observe Daylight Saving Time. If your time zone participates in daylight saving time, add the time difference to the file's offset-adjusted time when daylight saving time is in effect. UTC time is not adjusted to reflect daylight-saving time. For example, if your local time offset is -8:00, and if the file's UTC time is shown as 00:00 (12:00 midnight) on Monday, the adjusted time is 16:00 on Sunday (4:00 P.M., Sunday). The time setting when adjusted for offset is 06:00 (6:00 A.M.). The number at the bottom of each zone specifies the number of.

For example, -5:00 is the local time offset for Eastern Time (US & Canada):Īdd the local time offset to the UTC time.įor example, if your local time offset is -5:00, and if the UTC time is shown as 11:00, add -5 to 11. Universal Time (UT or UT1) is a time standard based on Earths rotation. The local time offset is shown at the start of each local region list item. If your local time zone is not selected, click it in the list of available time zones. To do this, follow these steps on a Microsoft Windows-based computer:Ĭlick Start, click Run, type timedate.cpl, and then click OK.Ĭlick the Time Zone tab, and then verify that your local time zone is selected.

If the time is 07:00 UTC, the local time is 02:00 in New York (UTC−5) and 10:00 in Moscow (UTC+3).Ġ7:00 UTC is also written more simply as 0700Z (or 07:00Z).
