P: Auto-Stack By Capture Time sometimes stacks photos incorrectly

Auto-Stack By Capture Time sometimes stacks photos whose capture times are separated by more than specified by Time Between Stacks. To reproduce:

1. Create a new catalog.

2. Make a copy of a raw.

3. Import the raw and its copy into the catalog.

4. Select the copy, do Metadata > Edit Capture Time, and change its time to one year earlier.

5. Do Photo > Statcking > Auto-Stack By Capture Time, with Time Between Stacks set at the default 0:08:00.

Observe that the the two photos are stacked, even though their capture times are separated by a year:

Doing Metadata > Save Metadata To File followed by Read Metadata From File and then auto-stacking doesn't avoid the bug.

I've observed that sometimes exporting the catalog as a new catalog avoids the bug, sometimes not.

A couple other recent reports of similar symptoms:

Yet another symptom of the broken internal architecture for storing photo capture times.

Tested on LR 10.4 / Mac OS 11.3.1.

"Update to OS X Sonoma 14 / LRC 13.0.1 seemed to fix stacking issue in my case"

Excellent. Unfortunately, I just retested the bug recipe at the top of this thread in my LR 13.0.1, and it's still failing.

Stacking issue is back 😞

Again one camera works, the older one once again does not.

Sonoma 14.2.1

LRC 13.2
