Yes.

Is there a setting I can apply to the file to allow all users to access it?
Like a group setting. Or is it hopeless?
Access (read, write, execute) is not the same as change file characteristics (access permissions, owner ID, group ID, and timestamps).

If a file has access permissions 666 (read and write by owner, group, and world), anybody can set the modification and status change timestamps of the file by writing to it and anybody can set the access timestamp of the file by reading it (but you can only set those timestamps to the current time; not some arbitrary time in the past, the present, or the future as you can with utime()).
