aqDateTime has AddDays and SubDays an interesting find

aqDateTime has two functions. When looking at the documentation for  aqDateTime methods, we dont see SubDays, but yet this function exsists. 

https://support.smartbear.com/testcomplete/docs/reference/program-objects/aqdatetime/methods.html

If i type in aqDateTime.SubDays("01/02/2017", 1) you would expect the result "01/01/2017" but that isn't the case.

It seems as if aqDateTime.SubDays acts exactly the same as aqDateTime.AddDays. 

The result above will come out as "01/03/2017".

Very strange, i do not suggest using this feature as it does the same thing as add days when expected to do the opposite.

Yes i get that i can go AddDays (date, -1)

Just posting an interesting find

    Using undocumented features is always a risk. They may be used for internal needs only and you never know why and how.

     

    I remember a strange issue about TestComplete about 10 years ago, when it was impossible either to declare a variable MSG or to use it correctly. It was related to some internal variable with the same name.

      Actually, I just tried in TC 12.40 to use aqDateTime.SubDays... and I got an "unknown identifier" error.

      What version of TC are you using?

        You know what, this is interesting. I was running the function through a script extension, no errors but treated it like AddDays.  HMMM

    LOL, the issue is still here :)

     

    Try running this code anywhere and you'll get JScript Runtime Error

    MSG = 'any text';
function test1()
{
  Log.Message(MSG);
}

    Change the name MSG to anything else and it will work just fine :)
