Your computer clock

It can synchronize once a week with the US government time lab’s atomic clocks. You can set your clocks by it. I routinely set it to synchronize time with the server once per week. You can access this by double-clicking the time in the bottom right of your screen. Then choose the Internet Time tab. In Windows 7, click ONCE on the clock on the bottom right. Click on Change date and time settings. Click on Internet Time settings, Change settings.
