+Support system dates back to the year 1970
+
+The system time on Linux can be set back as far as 1970 (the epoch time).
+Currently logrotate stops working correctly if the time goes before 1996.
+This value (1996) appears to have been hard coded since the code was written
+back in 1996. Testing and code analysis shows this can simply be modified
+to 1970.
+
+The patch is provided by Matt Bennett <matt.bennett@alliedtelesis.co.nz>
