Description

With 2.1 servers, our 1.8 clients are showing an incorrect date of:

1901-12-14 12:45:52.000000000 -0800

for newly created files.

Andreas has pointed us at a patch for LU-221 that looks like the cause of the problem.

We are in production with some 2.1 servers now, so we will need a quick fix on this. The LU-221 cure may have been worse than the disease, so I am going to start a build of our tree with that commit reverted.
