Dynamic session timeout

[Sam T]

Hi Alan and Arran

Thank you for your feedback. So if this expression is indeed corrected now,
i guess my question lies with how to handle the output.

It appears that the function to get WISPr-Session-Terminate-Time as an
integer is resulting in a blank value

  if (reply:WISPr-Session-Terminate-Time) {
            update reply {

        # Session-Timeout :=
"%{expr:%{integer:reply:WISPr-Session-Terminate-Time} - %l}"
        # Session-Timeout := "%l"
        Session-Timeout := "%{integer:reply:WISPr-Session-Terminate-Time}"
            }
        }

Specifically,

Session-Timeout := "%{integer:reply:WISPr-Session-Terminate-Time}"

results in a blank value

/////

This returns noop

%{expr:%{integer:reply:WISPr-Session-Terminate-Time} - %l}

the value being returned is not what we are expecting / Session-Timeout =
2753857926  / 2.7 Billion seconds is not what we were hoping for /
2753857926 seconds ago was July 28 1931

So, my question is, is the nested function,

{integer:reply:WISPr-Session-Terminate-Time}

actually converting into seconds or is it the value compared to epoch?

Any additional direction on how to handle the output, if correct, would be
greatly appreciated.
