Check the cell that has the date and see if the contents are one of the
following Excel functions:

=NOW()
or

=TODAY()

Both of which update based upon the current system clock. The NOW function
returns both date & time, and the TODAY function returns only the current
date.

When I open an attachment, the date on the spreadsheets changes from the date
they sent it to the current date.

How do I fix this?
