Login Screen Uptime 10 Hours Why?

When I first installed 6.3.0 at the login screen it said Uptime: Less then one hour.

It had my host listed as “localhost” so I changed the name and rebooted. Now my uptime always shows as 10 hours, why?

How can I make this thing work properly, or get rid of it in the login screen?

THANKS

Can anyone please tell me how to fix this, I can’t find anything in the Help manual.

THANKS
