TIME--Notes Specifying an invalid TIME format If you specify the time in an invalid format, MS-DOS displays the following message and then waits for you to specify the time: Invalid time Enter new time:_ Changing the TIME format You can change the TIME format by changing the COUNTRY setting in your CONFIG.SYS file. For more information, see the command. Depending on the country code, MS-DOS will display the time in the 12-hour format or the 24-hour format. If you are setting the time in the 12-hour format, be sure to specify P for hours after noon. Ensuring that MS-DOS prompts you for the time If you want MS-DOS to prompt you for the current time whenever you start your system, you can add the TIME command to your AUTOEXEC.BAT file. MS-DOS will automatically prompt you for the time and date if you do not have an AUTOEXEC.BAT file.
