For what it's worth, I wrote a simple test program to show a moving second hand, including a checkbox to make it sweep or tick; it's "secondHand.exe" and can be downloaded from
http://sickinger.net/download
The code for this has also been posted, it's "sh_main.pas". (Because I'm a pascal programmer.) The key code (that would be applicable to the MA3 clock) is less than 25 lines. (For initialization the lookup tables
and drawing the second hand, with an option for sweep or ticking.)
