What Would Cause Image Capture Time To Be Off?

[DroneSketcher]

Out shooting one building, capture time was right (11:11)
Turned off drone and remote
Moved about a block to take some pictures of another building
And the image time is way off (08:42)

What might cause this?
Does it get the time from the satellites?
Looking at the meta data in Lightroom Classic

0428 was taken no more than 5 minutes after 0427
Yet the time shifted so much

I had this too, on my first flights however only abroad and wondered why time is not received from the GPS signal.
But the last month it just worked fine at home.

I might assume, as I was abroad I did not hook the RC to any local WiFi but only before lift off to my phone's hotspot. Seems that was sometimes too short or not enough but I could not replicate it anymore.
