[DCP-o-matic] KDM time specifications: cinema local?

Hi all, It occurred to me that when specifying KDM time windows we should probably use time local to the cinema that the KDM is for. That is, if I made KDMs for cinemas in London and New York, and specified a window of 13:00-16:00, those times would be set so that the London KDM would open at 1pm London time and the New York KDM would open at 1pm New York time. This would require that the UTC offset for each cinema in the database was set correctly. Does this seem like a good idea to those of you making KDMs? Kind regards, Carl
