I've installed Tiger on two machines, an iBook and a PowerBook G4. In both cases the timestamp on incoming POP server mail is recorded in GMT, rather than my local timezone (EST). I've found a workaround -- listing mail by date sent, rather than date received -- but it irks me that the problem persists. Several of us have posted threads on Apple's discussion boards, and several obscure fixes have been proposed, but none of them worked for me. Are you aware of the problem? Do you know how to fix it?
