Set a computer clock to show the correct date and current time for your time zone. The clock that displays a time on your computer screen is subject to running fast or slow like other clocks, but Internet access can be used to correct that. Windows offers an option to set a computer clock for periodic time-correcting updates from its Web-based clock or your choice of timekeeping sites.
How to Set a Computer Clock
Double click the time display on the bottom right of the computer screen to open the date and time properties box. Use the tabs to access settings for time, date, time zone and Web-based time updates.
