Hi all What date system does GEDmatch use. Re the following dates in the UK are - 2015-07-10 12:11:45 = 7 October 2015 2015-07-06 12:51:45 = 7 June 2015 2015-03-09 21:13:01 = 9 March 2015. I have duplicate GEDCOMs uploaded and I think I should delete these two 2015-07-06 12:51:45 = 7 June 2015 2015-03-09 21:13:01 = 9 March 2015. Mike in Droitwich, England
