Could you be more specific?
The company I work for has a complicated system.
First there's the normal block time.
Then there are 3 sorts of duty time.
- duty time counting for salary
- duty time counting for rest time
- duty time counting for FOM limitations
All these duty times have their own rules and exceptions.
Not easy to understand and causing some discussions with crew control now and then, whether a duty is permittable or not.
