the field contains now a time in UDC-0 (instead relative to local UDC offset) this fixes a bug in peer selection, where an iteration over all seeds ordered by lastseen did not work correctly. Problems may occur because the new meaning of this field may mix with the different meaning of that field in older peers git-svn-id: https://svn.berlios.de/svnroot/repos/yacy/trunk@3322 6c8d7289-2bf4-0310-a012-ef5d649a1542
