Date functions

[Kernelpanic]

@mdijkens - You can do these and other date/time related things very easy with the library I posted above.
Just add to your program and calculate differences, leapyear, weekdays, daylight saving, timezones, etc.

Thank you for your hint. The key point about "DateDiff" is, how should I use that for calculations?
I know "DateDiff" from VB-Script and from Visual Basic, and there I used it for calculations in financial programs. I was able to use the result of “DateDiff” when calculating the repayment amount of loans.

Back then, I recalculated all formulas and results in all programs using a calculator, and when "DateDiff" was used, for example, it always delivered a correct result.

There can't be even the slightest mistake in finance. . . otherwise the Third World War will break out.
