Not any earlier time, but only the exact earlier time at which Subversion wrote an unchanged file. Without this optimisation large working copies would be extremely slow. $ svnadmin create repo $ svnmucc -mm -U file://`pwd`/repo put <(echo xx) f $ svn co file://`pwd`/repo wc $ stat wc/f | grep Modify Modify: 2016-03-04 15:15:25.927354821 +0000 $ echo zz > wc/f $ svn st wc # timestamp younger so modification detected M wc/f $ touch -d '2016-03-04 15:15' wc/f $ svn st wc # timestamp older so modification detected M wc/f $ touch -d '2016-03-04 15:15:25.927354821' wc/f $ svn st wc # timestamp equal so modification not detected $ -- Philip Martin WANdisco
