Time unit is not right in uvm testbench

UVM
,
1

When I want a delay in uvm case, I use “#5ms” in the case, but the actual delay is 5us.
Then I add compile option “-diag timescale” in compilation, and the timescale in “tb” is “1ns/1ps”.
And I do a few test about the time unit:

//////code begin
$display(“time 0 %0t”, $time);
#10;
$display(“time 1 %0t”, $time);
#10us;
$display(“time 2 %0t”, $time);
#1ms;
$display(“time 3 %0t”, $time);
//////code end

the output is:
time 0 0.220 ns
time 1 0.230 ns
time 2 10.230 ns
time 3 1010.230 ns

It is obviously that the time unit has become 1000 times shorter than the actual one.
Why?

In reply to ZEKU:

It is reporting time format in “us” and suffix string used “ns”.
Use/fix the $timeformat(unit_number, precision, suffix_string, minimum_field_width );


`timescale 1ns/1ps

module tb;

initial begin
#220;
$display("time 0 %0t", $time);
#10;
$display("time 1 %0t", $time);
#10us;
$display("time 2 %0t", $time);
#1ms;
$display("time 3 %0t", $time);
end 
initial begin 
    $timeformat(-9,3,"ns",12);
end 
endmodule 

//output
time 0 220.000ns
time 1 230.000ns
time 2 10230.000ns
time 3 1010230.000ns
