There is no metadata column within the Project Panel that consistently represents the time & date that video footage was shot. 'Date Created', 'Date Modified' etc., are always either randomly different to the actual date or missing altogether. However there is a column in 'Media Browser' that does consistently show the exact time and date that the footage was shot, no matter which camera it came from. This is called 'Date Last Written' and it can be found under the 'File Directory' option under 'Edit Columns...'
Can we please get this added to the metadata options within a Premiere project so we can finally start sorting multiple cameras by time and date?
