Witnesses don't care about 607. That is true . Because it means nothing in their mind. I similarly never gave the date any thought as it was just a date witnesses said and I said whatever.
However! 1914 is a date witnesses have a fervor and veneration for in a near idolatrous level. And the key (whether they know it or not) is a lie that is 607.
It's about 1914 and them lying blatantly for over a century. So yes and no. They don't care about the date but I don't think they know it's fabricated. Some witnesses need to learn it to know they are being lied to.
