Is request time available in VCL?

[Jean-Baptiste Quenot]

Hi,

I'm using a varnishncsa patch that logs how long the server took to reply:

    case SLT_ReqEnd:
        if (sscanf(ptr, "%*u %*u.%*u %ld.%*u %lf %lf %lf", &l,
&idle_t, &proc_t, &xmit_t) != 4) {
            lp->bogus = 1;
        } else {
            t = l;
            lp->df_D= (proc_t + xmit_t) * 1000000;
            localtime_r(&t, &lp->df_t);
        }
        /* got it all */
        return (0);

I'd like to add a X-Varnish-Time header in the response to indicate
the same number, for service health checks.  Is this time information
available in VCL?

Thanks in advance,
