Tests with git-filter-branch on a repository that was converted from CVS and that has commits reaching back to 1999 revealed that it is necessary to parse dates before 2000/01/01 when they are specified as seconds since 1970/01/01. There is now still a limit, 100000000, which is 1973/03/03 09:46:40 UTC, in order to allow that dates are represented as 8 digits.
