Screen grab of Files, showing 'Yesterday' under modified column.

I have a photo that I took on Sunday the 6th of March, Today it is Tuesday the 8th of March.  The file manager is listing the file as modified 'Yesterday' (modified column).

The time and date in Gnome's top bar is reporting today's date correctly.
