AlwaysTimed<T> class final

Represents the timed always operator G_I φ (Globally within Interval).

Asserts that the operand formula φ holds true at all points k in the trace suffix starting from the evaluation point i, such that the time difference timestamp(k) - timestamp(i) falls within the specified interval I.

If no points k fall within the interval I relative to point i, the formula is considered vacuously true.

Example: AlwaysTimed(isStable, TimeInterval(Duration(seconds: 1), Duration(seconds: 10))) asserts that isStable holds continuously between 1 and 10 seconds from now.
