Record to SD card without the internet/Wifi (offline)

Hi, my Wyze cam 2 lost WiFi Functionality, probably a hardware issue due to power outage, it’s been a couple of months now. It continues to work in offline mode, recording stuff on the SD card, but there is one main issue with that. It relies on actual date and time to operate, which it used to update from the internet. Nowadays, every time I unplug or loose power to the cam, it goes back to recording at date 1970, overriding the wrong files when storage is full, and mixing old files with new files.
Is there any solution I can do related to this? To keep the camera useful?
Not sure if travel mode covers this, is there a way to enable travel mode by connecting the cam to a laptop through USB? perhaps by flashing a special firmware for this purpose?
I would appreciate it a lot if the firmware keeps track of latest date and time used in a file somewhere, and reverts to those when it can’t access internet…
