Timescale problem

In reply to moustafaali:

I am running Code 1, and getting the correct output. What run commands are you using?

// Code 1
`timescale 1ns/1ps
module timing;
  initial begin
    $timeformat(-9, 3, "ns", 8);

    #1.0ns $display("%t", $realtime); // 1.000ns
    #2.0ns $display("%t", $realtime); // 3.000ns
    #0.1ns $display("%t", $realtime); // 3.100ns
    #41ps $display("%t", $realtime);  // 3.141ns
  end
endmodule


Output --
# run -all
#  1.000ns
#  3.000ns
#  3.100ns
#  3.141ns
#  quit -f
