How do you add the date and time to photos on HTC one X?

To add the date and time to photos on an HTC One X, open the Camera app and go to the settings menu. Look for an option labeled "Date & Time stamp" or similar, and enable it. Once activated, the date and time will automatically be included in the corner of your photos when you take them. If you want to add date and time to existing photos, you'll need to use a photo editing app that supports this feature.
