Yes, I first tried something similar; that is, I tried advancing by minutes.
Thank you for verifying that your results are similar to mine.

So I will now assume that the problem is not JScript or my use of it. I
seldom use JScript; the language I use primarily is C++ and for scripting I
primarily use VBScript. I chose JScript for this, for no particular reason.
Date and time arithmetic seems to be less convenient and less obvious for
JScript. I will try to implement this using VBScript and/or C++. I will post
results here when I have something useful.
