What does "Timestamp is too far from current time: 1396853746' mean?

I have installed the Google Analytics plugin and network activated it. Google Analytics site is showing real time data, but cannot see the stats on the network admin panel.

Thought I had to login to the Google account in the analytics plugin settings, but kept getting this message:

Timestamp is too far from current time: 1396853746

Could be a conflict caused by recently logging into the account on the development blog prior to going live on the production server?
