Using the latest private build from https://tools.taskcluster.net/index/artifacts/#gecko.v1.mozilla-central.revision.linux.2f6ea66057fe37794d7fc061407495cdcece5443.aries/gecko.v1.mozilla-central.revision.linux.2f6ea66057fe37794d7fc061407495cdcece5443.aries SD Card is set as the default internal storage. I took some pictures first using internal and then switched to SD card. STR: 1. Open Camera and take some picture 2. Open USB storage and move the pictures to my desktop (Mac) 3. See attached screenshot
[Blocking Requested - why for this release]: Blocking because we should show the correct date for each picture taken.

It is because the current time on the phone is changing.

System date is good. It's MTP that is getting crazy.

This affects all files (and folders) as far as I can tell -- not just camera pictures. e.g. with my Aries device mounted via MTP, I just created a new folder on it. The brand-new folder's "last modified" date is Jul 4 1993. Several minutes later I created another new folder; that one is displayed with "last modified" Jul 6 1993. Several minutes later, a new folder ended up with "last modified" Jul 7 1993. So they seem to be monotonically increasing, but way faster than real-world time. I wonder if we're somehow mixing up the date vs. the time, somewhere in our MTP code, or something like that...
