Something strange is afoot with dates in Lightroom

This is a weird one, so apologies in advance for the lengthy post. I noticed that some of my photos aren't sorting correctly by capture date in Lightroom/Lightroom Classic. As background, I'm using Lightroom Mobile on iPhone/iPad, and Lightroom + Lightroom Classic on a Mac laptop. As one example, I took a bunch of pictures on Dec. 29th around 11pm on my iPhone with the Moment Pro Camera app. I imported these into Lightroom Mobile, and edited them in the Lightroom app on my laptop. Looking at these images' full EXIF data in LRC, the Date Time Original property says I took them on Jan. 10th, 2025 - which, as I'm typing this, is six days from now. Date Time and Date Time Digitized say the correct date of Dec. 29th. According to ChatGPT, the offset is exactly 13 days and 8 hours apart, which is totally meaningless to me.

The source files are also correctly saved on my local machine in folders organized by date. There are a bunch of other images with similar discrepancies, and I can't figure out a) when this happened, or b) if there's a pattern with the amount of time that the actual date and the incorrect date are offset by. 

Has anyone seen this kind of thing before? Do I live in the multiverse now? Help!
