The following start 9 threads that each wait 6667 milliseconds.
The program run in 6.73 secondes and has the following output : 00:00:06.7116711|604140408
Where "604140408" is the number of tick.
There are 10 000ticks is a millisecond.
So this give ~60.414 seconds. Total execution time and wait time don't have the same output format for golfing reason.

using t=DateTime;var s=t.Now;Task.WhenAll(new t[9].Select(y=>Task.Delay(6667))).Wait();Console.Write(t.Now-s+"|"+(t.Now-s).Ticks*9);

Here is a fiddle that exceed the limit of execution of time of fiddle. Lower "6667" so that it fix fiddle's criteria if you want to run it.
