Time ontology for opening hours and events

Hi all,

I am looking for a time ontology that allows to express opening hours 
and event time.  This includes representation of opening hours with 
exceptions (e.g. holidays) or summer/winter time.

For events we need a model for language analysis, so we ideally need 
something that models "time of speech", "time when the event that is 
spoken about happens", "reference time".

Could someone give me a tipp?
We hope to find something that works in practice or a theorethical 
model, that can be implemented easily in practice.

All the best,
