If you want to add a date or time stamp to an iPhone picture, there are a few different ways to go about it. One way is to use the built-in camera app and take a picture with the date or time already added. To do this, open the camera app and select the photo you want to add a timestamp to. Next, tap on the three lines in the bottom left corner of the screen and select “Date & Time” from the menu that pops up. You can also use third-party apps like Date & Time or Timestamps if you want more control over how your timestamp looks. Once you have chosen an app, open it and select a photo from your library. Next, tap on the “Date & Time” button at the top of the screen and choose where you want to add your timestamp: on the photo itself (default), in a caption below it, or both. Finally, if you just want to quickly add a timestamp without having to mess with any apps, there’s always QuickTime Player (which comes preinstalled on most Macs) or iPhoto for Mac (which is available as a free download). Just open one of your photos and click on QuickTime Player/iPhoto’s “Timestamps” button at the bottom of the window. This will automatically add a timestamp and save your photo with that time stamp attached! ..
