Hi all...
In the following example, i would to add the "diff" value (in days) to a certain date (or the today's date "auj") >>

import std.stdio;
import std.datetime;
import core.time : Duration;

void main()
{
  auto deb = DateTime(2019, 9, 5);
  auto auj = Clock.currTime();
  writeln("Aujourd'hui : ", auj.day, " ", auj.month, " ", auj.year);
  writeln("Le début : ", deb.day, " ", deb.month, " ", deb.year);

  Duration diff = cast(DateTime) auj - deb;
  auto ecart = diff.total!"days" + 1;
  writeln("Diff : ", diff.total!"days" + 1);
  writeln(ecart);
}

Thanks for replies...

just use the plus operator

auto newTime = Clock.currTime() + 5.days
