What do you mean by 3M or aspect ratio of Digital Camera? Lumix Dmc-FZ28?

I just purchased Panasonic Lumix DMC-FZ28. I've noticed follows. When I take a picture, the camera date and time. However, there is an option to make date and time. When I try to do so, the system automatically resize the image to 3M. I do not understand what this means 3M? Does this mean that my 10-megapixel image is resized to 3 megapixels? Am I compromising my image quality? In addition, the manual referred to in the aspect ratio, what does it mean? What is 4:3 or 3:2 or 16:9? What are these? Final question. The date and time on the Lumix is rather small. Is there any way to increase the text size? I would be grateful if someone gives me the answers. Thanks!

What does the manual say about the time stamp? Images taken with a digital camera with the date and time encoded information in the image file as EXIF header. Any display device program can bring to these EXIF data so you can see the date, time, focal length, f-stop, shutter speed, ISO, and a host of other data. There's really no need for the time stamp on the photo ugly unless you have a specific reason to do so. The relationship aspect is the X: Y (horizontal: vertical) ratio of the dimensions of the image. Therefore, 4:3 means that the horizontal extent is 1333 (4 divided by 3) times the vertical extent of the photo. It's kind of a silly feature as you are throwing away data if you use the non-native aspect ratio of 3:2 (native to DSLR sensors) and 16:9 (format high-definition video). It's just a way to trim your images. The camera sensor is a 4:3 aspect ratio, more or less standard for point and shoot cameras.
