I'm sure this has been asked many times, but does changing the EXIF data using ExifTool on a JPG cause quality loss with recompression?

I'm specifically interested in changing the date on photos taken from my camera shot in JPG, where the year was off by one, but I want to make sure I don't lose image quality when the JPG is saved again with the updated "Photo Taken" timestamp.

No. Exiftool only edits metadata. It has no ability to change any image data.
