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.
Wouldn't that make local noon midnight?
Yes, that's the whole point. Astronomers (the non-solar kind) like it when the date doesn't change in the middle of their work day. If you use am/pm style timestamps, it gets somewhat confusing (unless you read "m" as "media nocte" rather than "meridiem" :-) ) but with 24 hour timestamps it's pretty reasonable. paul
