Issue 59862

Background:

Date fields (not fixed date fields) currently update to the current date as soon
as you open the document.  In my experience, these fields are typically used to
record the date of the document, meaning the date it was last updated, and are
used so the author doesn't have to remember to manually change the date.  

Issues:

-1- you can't open a document to find out when it was last edited (and, if it is
the version you want) because the date changes as soon as you open it, and

-2- if you open the document to print it, the printout has the date the doc was
printed instead of the date it was written.

Possible solutions:

-1- do not update date field values until the "dirty" flag is set indicating the
document has been modified, i.e. change the date value when you ungrey the Save
button.  

-2- push the date value change onto the undo stack so that if you undo your
changes back to the point where the save button is grey again, the date is restored.

-3- if enough people like the current behaviour, a new field type can be added
with the proposed behavior, perhaps called "date modified".  personally, I think
the change should be made directly to the date field.
