An interval var is often used in scheduling. Its main characteristics are its start position, its duration and its end date. All these characteristics can be queried, set and demons can be posted on their modifications. An important aspect is optionality. An interval var can be performed or not. If unperformed, then it simply does not exist. Its characteristics cannot be accessed anymore. An interval var is automatically marked as unperformed when it is not consistent anymore (start greater than end, duration < 0...)

Interval Var.
It's good to have the two extreme values being symmetrical around zero: it makes mirroring easier.
