Subject: [PATCHES] date/time timezone patches (mail bounced?)

Here are some hacks to get timezone behavior for the various time
data types to be compatible with v6.0. Although we have some hooks
already installed to get timezone info from the client to the
server, it still isn't clear if that can correctly transfer enough
timezone info to make the behavior the same as if timezone info
were derived from the server as is now the case. We certainly
won't resolve it in a day, so I think we are stuck with server-only
timezones for v6.1.
