4. URL Query Parameters
These are the recognized parameters for the Freebusy read URL which relate to the desired range and format of the returned data.
None of these parameters are required except for the conditions noted below. Appropriate defaults will be supplied by the server.
Implementation Notes: Date-only start and end times, i.e. a date/time value without a time component (e.g. 20080101), are not supported because time zone support would be required.
