The PW should be replicated but the pwdLastSet attribute, I think, is not. This acts similar to obtaining a user's LastLogin and LastLogoff via WinNT: provider in ADSI.

I have five sites. Most machines (about 775 total) that are in the site where the PDC emulator is located at look (?) accurate. There are five servers at two of the other sites that I installed that return the number of days since I added those servers to domain originally, four months ago.

I've just ran dcdiag, ntfrsutl, and repadmin tests on each of the eleven DCs. All tests were good.
