Hi Rog,
I am certainly no expert here but I'm recalling that the date Etc. is dependant on the Wi-Fi dongle.
The dongle isn't always connected so may not update all the time.
Whether connecting to a computer via USB host Etc. would allow you to modify files may be worth a look.
Are you asking so that it makes it easier to find files? Maybe prefixing the name with 001, 002 may help.
I'm probably no help at all. There will obviously be more people on here with lots more experience.
Good luck in your quest.
Bryan
