Timelapse videoe files have wrong date and time in LAN only mode

It is not a big deal, but my X1 Carbon still thinks it is March 2024, according to the file date of the time-lapse videos. I believe the reason is that I run in LAN only mode. Can I set the Data-Time manually? I guess no.
Turn LAN only off, then on again?

Did you ever find a fix for this? I have the same problem. Date and time on videos are off.
