    Very confused here

    It will not allow keys I know to work , other than some very secure ones that are not your business or need to know since this is an unknown site. 👎 SO IS THE KEY THE ONE IN MY MAILBOX?

The clock oscillator is a PLL, so is capable of being pulled into synchronized with the NTSP.pool atomic clocks. The android version of the Atomic Clock app made the display keep time with the net, and those internal clocks were 2-5 seconds off. Go copy one of those.
