MobileRead Forums - View Single Post - Source of 'timestamp' Data in "Device" 'Date' Column

Sorry for resurrecting this, but I was wondering about something.

I'm accessing an Onyx Boox Nova3 via USB from Calibre 5.14 from Windows 10 and also noticed the Date column in Device view being 01 Jan 1970. The weird thing is, when displaing the same files on the device in Win10's file manager, is shows correct dates/times in a its "Changed" column, and empty fields in its "Created" column.

So it looks like the Nova3 actually does correctly track the timestamps and is able to return it to other devices when asked in certain ways. The question is, what is Win10's file manager doing differently than Calibre when asking the device for the files' timestamps...

(What's also slightly curious is that within its own file system, Win10 calls the columns "Change Date" and "Creation Date" instead of the "Changed" and "Created" with the connected Nova3.)
