Getting back to the original question I posted: I was looking at how other languages have reached a point where certain "standard" functions have been incorporated into the base scripting engine because they had become so widely used. Things like string manipulation, date and time functions, math and statistical operations, and in some cases database interface tools. It seems to me that date and time functions are pretty common and that maybe it's a good time to consider rolling at least two into the "core": DateDiff() and DateAdd(). I understand some would disagree, but this is the "suggestion" forum, so I'm just making a suggestion.
