#10818: Mountain Duck fails to set file modification times (MacOS, B2)
----------------------------+---------------------------
    Reporter:  highfalutin  |      Owner:
        Type:  defect       |     Status:  new
    Priority:  normal       |  Milestone:
   Component:  core         |    Version:  7.1
    Severity:  normal       |   Keywords:  mountain duck
Architecture:  Intel        |   Platform:  macOS 10.14
----------------------------+---------------------------
 When a file is copied into a Mountain Duck mounted volume, its
 modification date is set to the current time, regardless of the original
 file's modification time.

 == Steps to reproduce ==

 1. Mount a B2 bucket as a Mountain Duck volume in the Mac Finder.
 2. Choose a file created sometime in the past, outside the Mountain Duck
 volume.
 3. Copy the file into the Mountain Duck volume by dragging it between
 windows.
 4. Wait for the copied file to appear in the Mountain Duck volume.
 5. "Get info" on the copied file, and on the original file.

 == Expected behavior ==

 The modification timestamps for the two files should be the same.

 == Actual behavior ==

 The modification timestamp for the copied file is the time at which it was
 copied.

 In the Finder, when I copy the file, the copied file very briefly shows
 the correct modification date in the file listing, but after a second it
 changes.

 See attached video which shows the behavior.
