`Date.getVarDate()` function seems incorrectly defined

[samchon]

interface Date {
    getVarDate: () => VarDate;
}

TypeScript has defined Date type to has a functional property getVarDate, but such function does not exist in the real Date instance. Looking at some API documents, the Date.getVarDate() is a non-standard method forActiveX. Therefore, I hope TypeScript to remove the functional property or change it like below:

interface Date {
    // no reason to be property assigned functional value
    getVarDate?(): VarDate;
}

We should just remove it, not tweak the syntax. It doesn't even exist in Chromium.
