xbox 360 clock

My 360 clock is going up by a minute every month and is five minutes off now. Is there anyway to fix this?1man

The manual setting is grayed out.1man

Now that's weird. I can't imagine why it wouldn't let you manually change your time. Something sounds sketchy.

If you go to clock under console setting the date and time option is grayed out.1man

Not for me it isn't.
