* Signatures for functions computing new / postponed event wait time. New
* event wait time is the time till the next event if an event is currently
* being triggered; postponed event wait time is the time till the next event
* if an event should be triggered but needs to be postponed, e.g. when the TSD
* is not nominal or during reentrancy.

* These event wait time computation functions should be defined by the modules
* owning each event. The signatures here are used to verify that the
* definitions follow the right format.
