I don't think it can. I have not used LabVIEW for the FRC robots, I use it in my work, however, my understanding of how it works says you couldn't simply drop this in. However, you can adapt the concept of it (measuring the time between now and when you pushed the button).
On a simplicity note: Why not just have your drivers ensure they hold the button down for at least 30ms? 30ms is not a very long time, and chances are good that your drivers already ARE holding the button for this long. I remember always having to code my robots to trap the rising edge of a button, because if i used the buttons on/off state, I would read many more "on"'s than one.
EDIT: ie.
Code:
if( oldButtonState == off && ButtonState == on) {
//do some stuff
}
oldButtonState = ButtonState;
30ms is 0.03s. Roughly 30Hz, which is right around the same speed our eyes operate at.
