Excel "records" the date a file was saved, not when it's opened. Anything
else you might have Excel do, such as recording who opened the file and when,
etc, depends on the operation of macros. If the user does not enable the
macros, you have no control. To do as you wish, you would need VBA code
controlling the initial viewing of the file unless macros were enabled, and
when they are, then to do an immediate capture of pertinent data and save,
thereby recording such items regardless of whether the user intentionally
saves or not.
