To what your comment says, you would:

                set beresp.ttl = 120s;

because in VCL ttl is always relative to now.

I think the task is how do we express "Give this a total lifetime
of two minutes" and that would be:

		set beresl.ttl = 120s - beresp.age;

Yes, unless this discussion leads to better results.
