Lightroom truncates the "Date Created" EXIF timestamp which causes Photos.app not to recognize it

This is an annoying, sporadic problem, but I think I've finally figured it out:

When you use the "Edit Capture Time..." option to shift the timestamp of a photo (e.g. -5 hours),
If the photo's original timestamp has a 00 seconds component (e.g. "2016:08:23 22:23:00")
Then upon Export, Lightroom will truncate the seconds component of the timestamp (e.g. "2016:08:23 17:23")

Photos.app does not seem to be able to parse this truncated timestamp, and reverts to using the photo's original, unshifted timestamp.

I'm not able to reproduce that behavior. Here are the relevant date/time fields of a JPEG before using Edit Capture Time to shift the time by -5 hours:
[EXIF]          Date/Time Original              : 2016:08:24 10:29:05
[XMP]           Date Created                    : 2016:08:24 10:29:05
[IPTC]          Date Created                    : 2016:08:24
[IPTC]          Time Created                    : 10:29:05
[Composite]     Date/Time Created               : 2016:08:24 10:29:05
And here are the fields of an exported copy after shifting by -5 hours:
[EXIF]          Date/Time Original              : 2016:08:24 05:29:05
[IPTC]          Date Created                    : 2016:08:24
[IPTC]          Time Created                    : 05:29:05
[XMP]           Date Created                    : 2016:08:24 05:29:05
[Composite]     Date/Time Created               : 2016:08:24 05:29:05

(I used Exiftool to examine the fields).  As you can see, the seconds have been preserved.  So I wonder what's happening in your case.  If you post a sample pic (prior to having its time shifted) and the exported version (after shifting its time) to Dropbox or similar, we can troubleshoot in detail.

"If the photo's original timestamp has a 00 seconds component"

Oops, I missed that.  But even if I start with a photo with a 00 seconds component, I don't see LR's Export truncating the seconds.  So a sample photo and its exported version uploaded to Dropbox will help understand what's going on.

My apologies for the wild goose chase! I figured out this is actually a Photoshop problem rather than a Lightroom one.

I'm going to open a new issue in the Photoshop forum with a Dropbox download like you suggested.
