Forums Scripts & Popups Using $ctime with $duration

//echo -s Now: $date $asctime(HH:nn:ss) | echo -s Time since 22/02/2003 13:28:32: $duration($ctime(22/2/2003 13:28:32))

Gives me output:
Now: 22/02/2003 14:00:50
Time since 22/02/2003 13:28:32: 1729wks 2days 12hrs 28mins 32secs

What am I doing wrong here?
