startToCloseTimeout

If set, specifies the maximum duration a worker may take to process this activity task. This overrides the default start-to-close timeout specified when registering the activity type using RegisterActivityType.

The duration is specified in seconds, an integer greater than or equal to 0. You can use NONE to specify unlimited duration.

A start-to-close timeout for this activity task must be specified either as a default for the activity type or through this field. If neither this field is set nor a default start-to-close timeout was specified at registration time then a fault is returned.
