Remote account linking via Google has failed. Please make sure that the system clock is set properly

In order for the authentication function to operate, your server time must be within 30 seconds of Google's server time. This error indicates the difference between the two server clocks is outside the acceptable tolerance level (timezones differences do not cause this error).

To resolve this it is necessary to sync your server clock with a NTP server to ensure it is completely accurate. You can use any NTP server of your choice, but Google do offer their own. This can be done from the server command line and typically requires root access:

ntpdate time.google.com
