Add Date & Timestamp to Still and Time Lapse captured images. #1488
Description
I believe it would be very useful to many users if Mycodo had a feature which would overlay a basic date & timestamp on the Still and Time Lapse images. Using time lapse videos is very useful in calculating when watering times and intervals should be set to avoid water column collapse and wilting in plants... it would be very helpful in this respect to have an accurate timestamp overlayed on Still and Time Lapse captured images without having to use 3rd-party code or an external app. Trying to use a 3rd-party Linux app to add a timestamp to an already existing image is clunky and time-consuming at best and really doesn't work when running on the Pi parallel to Mycodo, especially when Mycodo is capturing a new image every few seconds for a time lapse video. And trying to offload those pics to a PC and add timestamps to an image sequence of thousands of images taken for compiling into a time-lapse video is excruciatingly slow and cumbersome... Is there some reason that Mycodo can't place a timestamp on it's image captures?
Was thinking of something like this timestamp at the top of the image...
Supposedly this code-block recommended by Google can add a timestamp to images... can this be added to the Camera Function?
