Why is this valued zeroed?

I stuck at this and can't figure out the reason why the value of
the variable ds is 0 when I do this: startTime =
MonoTime.currTime; if I remove that statement, the value of ds
isn't zeroed, it has the actual number of seconds. But I can't
figure out, ds is of integer type and such, it is copied, right?
or is this related to the fact I'm setting it withi a callback
function?
here's the piece of code:
> import std.net.curl;
> auto http = HTTP(url);
> http.method = HTTP.Method.get;
...
the relevant part:
> http.onProgress = (size_t dltotal, size_t dlnow,
> size_t ultotal, size_t ulnow) {
> if(dlNow > 0) {
> MonoTime endTime = MonoTime.currTime;
> Duration duration = endTime - startTime;
> long ds = duration.total!"seconds";
> writeln("duration!seconds = ", ds);
> startTime = MonoTime.currTime;
if I put startTime = MonoTime.currTime, ds is zero, otherwise, if
I remove it, ds has the actual value.
startTime is first set right before http.perform() call:
> startTime = MonoTime.currTime;
> http.perform();
(My goal is define the download transfer rate, different
approachs for this are welcome)
