Using system functions : $realtime and $time as arguments to format specification %t

In reply to dave_59:

Hi Dave ,

without using %t

I provide $realtime / $time as argument without a format specification %t

Eg : $display($realtime,," a == 6  @ T == %0t ",$realtime );

First part of the display is without %t and uses $realtime directly as argument ,
second part provides %t as format specification with $realtime as argument.

The output is different when I use %t with $realtime / $time compared to using only $realtime / $time
