Each of the fields in the CV Manager contain a date/timestamp of when they were last copied or edited. For example this appears to the right of each CV field, after the button:

The first field shows that the original CV was first referenced on 16th January 2007 and the second field shows that the first formatted CV was created on 20th April 2007. The buttons to the right of the date are as follows:
Edit the
document in Word.
Generate a CV
from the contact details.
Delete the CV
and remove the timestamp.
