   Change the time. The command for changing time in Command Prompt is time HH:MM:SS AM/PM where "HH:MM:SS" refers to the hour, minute, and second, and "AM/PM" refers to whether it's morning or afternoon. To change your computer's time, type in this command with your preferred time indicated, then press ↵ Enter.

   1. For example, typing in time 08:35:00 AM and pressing ↵ Enter would change your computer's time to 8:35 AM.
   2. To change the time to 10:00 PM, you would type in time 10:00:00 PM and press ↵ Enter.
   3. If you're comfortable with 24-hour time, you can type in your preferred time (e.g., 14:00:00 for 2:00 PM) and leave off the "AM" or "PM" tag.
7. 
   Change the date. The date format you'll use in Command Prompt depends on your country, but Command Prompt will tell you which format to use: type in date and press ↵ Enter, then type in the date you want to use in whichever format is specified by Command Prompt (e.g., "mm-dd-yyyy" in the United States) and press ↵ Enter.

   1. To change a United States computer's date to September 25th, 2018, you would type in date and press ↵ Enter, then type in 09-25-2018 and press ↵ Enter.
   2. To adjust the date to read October 12th, 2018 on a European computer, you would type in date and press ↵ Enter, then enter either 12-10-2018 or 2018-10-12 depending on your location.
8. 
   Review your computer's time and date. In the bottom-right corner of the screen, you should see both your updated time and your updated date reflected in your region's format.

   1. If you use 24-hour time, you won't see "AM" or "PM" listed here.
