How are intervals represented by Chronus?
An interval may be represented in Chronus by using the PERIOD clause, with an optional granularity clause. If a granularity is specified the datetime supplied to converted to that granularity. If the granularity is finer than the supplied start datetime’s finest granularity, it is converted to the last possible chronon at the supplied granularity; similarly, the granularity is finer than the supplied finish datetime’s finest granularity, it is converted to the first possible chronon at the supplied granularity.
