This correction keeps UTC in conjunction with the apparent position of the Sun and the stars, and it is the standard used for all general timekeeping applications. TAI is computed by the International Bureau of Weights and Measures (BIPM) located near Paris, France.Ĭoordinated 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. While the stability of TAI is achieved by this weighted average, the accuracy of TAI is derived from data from primary frequency standards, which are clocks built at several national metrology institutes. Thus, if N = 300, the maximum weight is 0.83 %. The most stable clocks receive the most weight in the calculation, but the maximum weight assigned to any clock is limited to A / N, where A = 2.5 and N is the number of clocks. These clocks are located at more than 60 timing laboratories around the world. International Atomic Time (TAI) is an international time scale that is computed by taking the weighted average of more than 300 atomic clocks. What are International Atomic Time (TAI) and Coordinated Universal Time (UTC)? It is distributed through the NIST time and frequency services and continuously compared to the time and frequency standards located around the world. UTC(NIST) serves as a national standard for frequency, time interval, and time-of-day. The clocks in the UTC(NIST) time scale also contribute to the International Atomic Time (TAI) and Coordinated Universal Time (UTC). The most stable clocks are assigned the most weight. The outputs of the clocks are combined into a single signal by using a weighted average. The number of clocks in the time scale varies, but is typically around ten. The UTC(NIST) time scale comprises an ensemble of cesium beam and hydrogen maser atomic clocks, which are regularly calibrated by the NIST primary frequency standard. UTC(NIST) is the coordinated universal time scale maintained at NIST. Why is UTC used as the acronym for Coordinated Universal Time instead of CUT?.What are International Atomic Time (TAI) and Coordinated Universal Time (UTC)?.How is UTC(NIST) related to Coordinated Universal Time (UTC) International Atomic Time (TAI), Greenwich Mean Time (GMT), USNO time, GPS time and Zulu time?

If you have any questions, feel free to post a comment. That’s about all there is to changing the time to military format in Windows. This is a really long way to get to the same dialog that you can get to in one click from the Control Panel. Here you have to click on the Change calendar settings link.įinally, this will bring up Customize Format dialog, where you have to click on the Time tab.

The other way to go about this in Windows 7, 8, and 10 is to click on the date and time in the taskbar and then click Change date and time settings.Ī new dialog will appear and at the top you have to click the Change date and time button.Īnother dialog will pop up where you can actually adjust the date and time manually. I’m not sure where the Short time format is used in Windows, but you can change that too in order to keep everything consistent. In order for the change to appear in the time shown in the taskbar, you have to change the Long time format.

Now in Windows 7 and higher, the Formats tab is front and center and you can change the time format from the Short time and Long time dropdowns.Īgain, the capital H is military time. If you are in Category view, switch to Small or Large icons at the top right.

In Windows 8 and Windows 10, it’s just called Region. In Windows 7, open the Control Panel and click on Region and Language. I explain the steps below for later versions of Windows.
Ironically, it’s faster to use the Control Panel in Windows 7 and higher. Microsoft has kind of done this in Windows 7 and higher, but it takes quite a few clicks to get it done. It would make much more sense to put the option in the Date and Time Properties dialog when you double click on the time in your system tray. Not a very straightforward process at all. Now click OK until you are back to the Control Panel.
Lower case h means 12 hour format and upper case H means 24 hour format.
Next click on the Customize button on the Regional Options tab.Ĭlick on the Time tab and choose any of the options with the upper case H.
