Gallery timeline shows ridiculously incorrect time for some pictures

Expected Behavior

The gallery timeline exhibiting pictures with correct grouping by time.

Current Behavior

This problem happens to only a small fraction of my pictures, which were (mainly) downloaded/saved by some Chinese social media apps, like Weibo and Baidu Tieba. After upgrading from nightly 20200429 to nightly 20200531, The gallery timeline shows that they are from ridiculously far future, like year 51510 AD, but meanwhile, the "Details" window still showed correct time of each affected picture.

UPDATE: after clearing the data of the system app named "Media Storage" & rebooting, there's no longer any ridiculous dates - however, all pictures just turned to be added today, which is still incorrect.

Possible Solution

I don't know, maybe it's related to https://review.lineageos.org/276724, which seems to be a fix of #1857 (closed)

Steps to Reproduce

I'm not sure whether this is reproducible - it unfortunately seems to be not, since I have tried to save some pictures in Weibo or Tieba once again, then these newly saved pictures went into the group of "May 2020 to March 50261".
