I have today transferred a number of videos from my smartphone to my tablet and in so doing the copied files all reflect the current date as opposed to the original creation date. This means that they do not therefore appear in date order for the purpose of viewing in date order.
I can change the file names alphabetically but that does not help as the tablet only allows display in date order.
It is many years since I changed the date attribute and cannot for the life of me remember the method.
I'm not sure this is exactly what you need, but maybe worth a look.
I used a program called Exifer for many years to alter the time of photos taken with one of my digital cameras (the camera's screen wasn't working so I couldn't see to alter the time).
I haven't used the program for a long time, but still have it installed, and note that you can alter the 'Date taken' and 'Date modified', in addition to the time.
