PHP schedules can now set workflow execution and run timeouts through the supported ScheduleManager API.
Pass executionTimeoutSeconds and runTimeoutSeconds to create(), or set the corresponding action fields in createFromSpec(). Manual triggers and automatic starts forward the same budgets. Updating a schedule changes future starts while preserving deadlines for runs already started. Omitted timeouts retain existing behavior, and PHP timeout values follow StartOptions validation.
The schedule guide includes runnable examples and explains execution versus run budgets. No database migration or worker protocol change is required.
