Microsoft uses the Coordinated Universal Time (UTC), an international standard of 24 hours to document creation dates and times of files that are included in a software update. This article describes how to convert UTC to local time to verify that the file is on your computer is the one described in the literature.
To convert UTC to local time, follow these steps:
1. Determine your local time offset from UTC. To do this, follow these steps on a Microsoft Windows:
1. Click Start, click Run, type timedate.cpl, and then click OK.
2. Click the Time Zone tab, then check your local time zone is selected. If your local time zone is not selected, click in the list of available time zones.
The local time offset is shown at the beginning of each list item local area. For example, -5:00 is the local time offset for Eastern Time (U.S. & Canada):
(GMT-5: 00) Eastern Time (U.S. & Canada)
2. Add the local time offset from UTC.
For example, if your local time zone is -5:00, and if time is represented UTC 11:00, add -5 to 11. The setting of time when they are adjusted to compensate is 06:00 (06:00).
Note: The date also follows UTC. For example, if your local time zone is -8:00, and if time the file is shown UTC 00:00 (12:00 to 0:00) on Monday, the adjusted time is 16:00 on Sunday (16:00 Sundays).
3. Set DST.
UTC is not adjusted to account for DST. If your timezone is involved in the summer time, plus the time difference in corrected time variations of the file when DST is in effect. For example, if the time in your time zone is one hour ahead of standard time, add one hour to the time shift changes.
4. Convert the 24-hour format 12 hour if your time zone uses the 12-hour format. To make the conversion, follow these steps:
* If the offset is adjusted to 12:01 p.m. to 11:59 p.m., inclusively, subtract 12 for the set time, then add PM
* If the adjusted time is 0:01 to 11:59, including leave time that is adjusted, then add AM
* If the adjusted time is 00:00, 12:00 to 0:00 using.
* If the adjusted time is 12:00, using 12.00.
* You can use this method to compare the time to convert the files to the time of a file update software on your computer.
* When viewing the details of the file is on your computer, the date in the Date Modified column may be different from the date in the Date column creation. If this difference occurs, use the date in the Date Modified column.
