== Description

Return a `TimeInterval` value that is the difference between the specified `lhs` and `rhs` time intervals. The behavior is undefined unless (1) operands of type `double` can be converted to valid `TimeInterval` objects, (2) the value on the right‐hand side (potentially after conversion to a `TimeInterval`) has a number of seconds that is not `LLONG_MIN`, and (3) the resulting time interval can be represented with a 64‐bit signed integer.

== Return Value

difference of `lhs` and `rhs` as a `TimeInterval`
