Pierre Joubert, SV/PROG - Pierre Joubert - date of birth

After many merges this profile reflects a very specific date of birth - 25 May 1663 - with the source not actually offering evidence of this. Generally the date is given as 1664 or 1665. Does anyone have source/evidence for this date other than perhaps other online trees? If this is reflected in other trees has that been followed through for a source?
