In Excel 2002 SP3 on Win XP, the workbook's file modification date changes to
the current date and time as soon as the Excel workbook is opened, even if
there are no changes applied to the file. If you close the workbook without
changing any of its contents, the file modification date reverts back to the
original value. Is there any way for the file modification date to remain
unchanged until afte the Excel workbook has been modified? Does this behavior
occur in newer versions of Excel?
