For instance, during summer months the UK switches from GMT to British Summer Time or BST. To account for this, some countries in the GMT time zone actually switch to another zone during Daylight Saving. Other time zones are designated by the hourly difference between Coordinated Universal Time.īelieve it or not, neither the GMT time zone nor the UTC standard are affected by Daylight Saving Time or DST. World timing centers across the globe have decided to keep their local clocks synchronized with the UTC standard. Contrary to popular belief, UTC is a standard even though it is mistaken for a time zone, which it is not. Greenwich Mean Time or GMT is the official time zone used in that region, which runs through several European and African countries.Ĭoordinated Universal Time is named as such because it is the standard by which all time zones are based. Since Coordinated Universal Time or UTC is a standard, there is no time zone, territory or country that uses it for a local time. If this difference occurs, use the date in the Date Modified column.Did you know that there is a difference between GMT and UTC even though they share the same current time? In short, GMT is an actual time zone, whereas UTC is a time standard that is used to keep time synchronized across the world. When you view the file details of the file that is on your computer, the date in the Date Modified column may be different from the date in the Date Created column.

You can use this method to compare the file's converted time to the time of a software update file that is on your computer. If the adjusted time is 12:00, use 12:00 noon. If the adjusted time is 00:00, use 12:00 midnight. If the adjusted time is between 00:01 and 11:59, inclusive, leave the adjusted time as is, and then append A.M.

If the offset-adjusted time is between 12:01 and 23:59, inclusive, subtract 12 from the adjusted time, and then append P.M. To make the conversion, follow these steps: Since Coordinated Universal Time or UTC is a standard, there is no time zone, territory or country that uses it for a local time. 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. 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). As an astronomical time scale, it followed the. Greenwich Mean Time (GMT) originally referred to the mean solar time at the Royal Observatory in Greenwich, England.

The time setting when adjusted for offset is 06:00 (6:00 A.M.). Coordinated Universal Time (UTC) is based on TAI, but it is adjusted by leap seconds to account for the difference between the definition of the second and the rotation of Earth.

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. The local time offset is shown at the start of each local region list item. (Image Credit: Jeff Hicks) With this I can import my log data and. If your local time zone is not selected, click it in the list of available time zones. I also added plenty of Verbose output so you can see what is going on in the function.
