Background to my question about DateDiff():

I wrote a little app for my Win Box in office:

if i klick on it, windows shuts down; Space & klick reboots and F1 & 
klick shows me a message box, telling me how long i have to stay in 
Office to fullfill the 8 h 30 min working time. Now i have my pension, 
starting 01.08.2018 and i thought: would be nice to know in this message 
box how many Years, Month, days left?!!

That how the story begins ... and lazarus would be better, if there 
exists a function DateDiff.

Meanwhile i googled again and learned. 29.01.2000 until 28.01.2001 is 0 
Y 11 M and 30 D in Libereoffice and MS Office 360.

I' ll look later in my Win on this computer to look what MS Access 97 
tells me.

What about Databases like mysql, Oracle, Firebird. I'm shure they have 
such a function.

.. lots to search for .. hihi ... my cooking is ready ... see you :-))
