Hi Kevin,
On rereading, your data is probably coming into one sheet,
I don't know if a change event will be picked up but you could
have whatever is entering the date. Is the date being added at the
end or simply replacing the existing cell. I suspect that I won't
be able to answer your question even if you give the missing
infomration.
------------------ if it were just if the workbook was updated ------
Don't know if this will serve your purpose or not
[a1] = "LastSaved"
[b1] = "Active when saved" (that is the sheetname)
[c1] = "active Cell"
[d1] = "UserName"
User controlled Save History as an alternative to Highlight Changes (#BeforeSave)

Be aware that volatile functions such as NOW() will cause
the change bit to be set forcing a File Save.
Note on browsers:
FWIW, the Firefox browser is sensitive to case within the local link (anchor)
so you would have to use lower case as it stands now. for #beforesave
Internet Explorer and other browsers as I remember them couldn't care less.
If you want to read more see my

I will probably change the visible wording. I can use a bookmarklet to
see what the ID (id=) really is.
