Time field
A time field is an arbitrary collection of timeslots.
It can be used to define various teaching limits for different time spans than days, such as afternoons or mornings.
Time fields can be found in the organisation section of the main navigation.
Timeslots
The time field screen allows defining the timeslots comprising the time field. Because timeslots are specific to each term, the slots in a time field can be different for each term. When you clone a term, timeslots within time fields are cloned too.
