Select "Set date/time and owner string..." from the Camera menu to display the "Camera Settings" dialog:
This dialog shows information about the camera and allows you to synchronize the camera's internal clock with your PC's clock and set the Canon camera owner string.
Please note: It may not be possible to sychronize all Canon cameras with the PC's clock to the exact second but it is possible for it to be no more than one second out of sync.
Select "Automatically synchronize clock when camera is connected" if you would like DSLR Remote Pro for Windows to automatically synchronize the camera's clock to the PC's time each time it connects to the camera.
