Display a millisecond timespan in Dynamics AX

Simple little job to get the juices flowing. It was nigh-on impossible to track down some code to do this natively within AX, they seem to have removed all decent tracing into some external tool. Not conducive to job-based hacking ;-)

static void Nathan_timeSpan(Args _args)
{
    CustTable ct;
    System.DateTime first, second;
    System.TimeSpan ts;
    ;
   
    first = System.DateTime::get_Now();
    sleep(123);
    second = System.DateTime::get_Now();
   
    ts = second.Subtract(first);
   
    info(ts.ToString());
}
