[SR-Users] Trouble getting start time / call duration from dialog module

Hi.

I wanted to update every one on this issue.

I found that while the dlg start time: $dlg(start_ts), DLG_lifetime:
$DLG_lifetime aren't populating I can still use the following to record the
start time of the call as a dialog variable:

$dlg_var(TVs) = $TV(s);

A strange problem with this however is that when I compare that start time
to the time when the bye occurs I see 10 extra seconds that never actually
happened.

In other words this:

$avp(elapsed) = ( $TV(s) -  $dlg_var(TVs));

sets my $avp(elapsed) to be 10 seconds longer than the call actually was.

I fixed it simply enough like so:

$var(dialog_duration_fix) = DIALOG_DURATION_FIX;
$avp(elapsed) = ( ($TV(s) - $var(dialog_duration_fix)) - $dlg_var(TVs));

I have worked around these issues for my own purposes but still seems like
there are some odd bugs here.

I hope this message finds every well.

All the best.
