the concept of passing time may be viewed as a simple passage (e.g. of a bus at a stop point) or as a longer stay (e.g. in maritime ports of call)

NOTE The attributes describing the waiting time in the subtypes of passing time, in particular, will be used to describe such a call. The attribute ‘alight and reboard’ will express the possibility for the passenger to alight for a while, during the passing time of a vehicle journey at a particular stop poing.

The passing times that are computed on a specific operating day are called dated passing time.

This entity has several subtypes; TARGET PASSING TIME, the latest official plan for a dated vehicle journey, on a point in journey pattern; ESTIMATED PASSING TIME, a forecast for a monitored vehicle journey on a point in journy pattern; OBSERVED PASSING TIME, recorded for a monitored vehicle journey, on a particular point.

In SIRI Passing times are subsumed into a CALL entity.
