How do I access system time in MatrixX v62.2?

Question

I have written a number of scripts (MathScript) to extract block information from my SystemBuild models.  I have thought that it would be useful to display the elapsed time after the script has executed, however the functions provided in the version that I'm running (MatrixX version 62.2) don't seem to provide what I'm looking for.  The function I am currently trying to use is clock() and its variants;
clock() - is no good, as it gives you the elapsed time since the last call.  If I write code that looks like this;
clock()
doSomeStuff()
elapsedTime = clock()
I can't be guaranteed that there are no calls to clock() within doSomeStuff(), so elapsedTime may not be the time elapsed since I called doSomeStuff().
I'm running on a windows xp platform, so clock({cpu}) does the same as clock().
Of course, I could use the clock({time}) and clock({date}) variants, convert them to a time in seconds since the start of the day or the month and just use that as a reference, but that just seems kinda wrong.  Although it is unlikely that anyone would be running these scipts at 12:00 at night at the end of the month, I know that somewhere along the way something had to know the system time to figure out the time and the date anyway.
Is this conversion performed by clock()?  What function(s) does it use to access the system time? Are they accessible directly from XMath?

Thanks for the feedback Bob.  I hadn't really considered using the negative result produced across 12:00 as a trigger for just adding another 24 hours to the result.  I can't see myself needing to run a script that runs for more than 24 hours, I just wanted some feedback so that I know how long they're running for.
I will attach a version of the mso that I have built in case anyone wants it (had to attach as a txt, as mso is not in the allowed list).
