availabilityStartTime
AvailabilityStartTime is a timestamp that marks the beginning of a defined availability window for a resource, service, or person. It indicates when the resource becomes available for booking, assignment, or use, and is commonly paired with an availabilityEndTime to define a complete time span.
In data models and APIs, availabilityStartTime is typically stored as a date-time value in ISO 8601 format
Common use cases include scheduling systems, appointment booking, workforce management, room or equipment reservations, and service
Constraints and validation typically require that availabilityStartTime precedes availabilityEndTime, and that the window aligns with business
Implementation considerations include efficient querying for time-based ranges (indexing on the start time), ensuring data consistency
