The traditional calendar for observing at Lick Observatory has always had days begin at local noon. This means that the time zone for the Lick calendar is 20 hours behind Greenwich.
You should be OK with tzcode or with any other POSIX-conforming implementation, since POSIX requires support for UTC offsets up to 25 hours. I don't offhand know what tzcode's limits are in this area; at some point integer overflow kicks in, if nothing else does.
