Can the following be interpreted only as 1(obligation) or 2(schedule) as well? I think depending on context, the meaning can vary, right?

ex)Linda is to come back here by 9 o'clock
=>1. Linda has to come back here by 9 o'clock
2. Linda is going to come back here by 9 o'clock.

Yes, context would make it clear.
