I'm successfully registering a SipProfile with 1 hour expiration. I see the REGISTER message in Wireshark on the SIP server machine, re-sent with authorization.

Brekeke replies immediately with a STATUS: 200 OK, passing back 'Expires:3600'.

Both Xamarin's and Android's docs tell me that lExpire should be duration in seconds before the registration expires, so it represents an interval. I multiply by TimeSpan.TicksPerSecond to convert to TimeSpan, 3600 would result in 0.01:00:00:

void    ISipRegistrationListener.OnRegistrationDone( string lclPrfUri, long lExpire )

{

    long    l=  DateTime.Now.Ticks;

    double  d=  (double)l / lExpire;

    string  s=  string.Format( "RegSucced( '{0}', {1} ), {2}, {3}", lclPrfUri, lExpire,

                    new TimeSpan( lExpire * TimeSpan.TicksPerSecond )

                        .ToString( "d\.hh\:mm\:ss" ), d );

    ..

}

But i'm getting values in the range of 1.5 trillions (1'541'195'345'242)!

As i saw it constantly growing with time, i thought it might be related to Ticks, so i exposed both and gathered the following statistics (H == T + 1 hour -- expected expiration):

    #  DT.Now.Ticks (T)     lExpire (E)     T/E ratio   T+36000000000 (H)   H/E ratio

    1  636767624266839520   1541183611836   413167.918  636767660266839520  413167.941

    2  636767669188704010   1541188122398   413166.738  636767705188704010  413166.761

    3  636767670260843180   1541188229643   413166.710  636767706260843180  413166.733

    4  636767670974718350   1541188301027   413166.691  636767706974718350  413166.715

    5  636767693193745790   1541190522922   413166.110  636767729193745790  413166.133

And the ratios look surprisingly consistent, though the magic of 413166 escapes me.. And from that lExpire looks more like a reference to a point in time, than an interval, no?

But according to docs i should get 3600 without any scaling factors, right? What is going on??!
