This error indicates that your system clock has been set incorrectly. Please check that your system date and time are correct.

To change the system date under Windows:

1) Click on the Start menu.

2) Choose Settings.

3) Click on Control Panel.

4) Choose Date/Time.

For Linux;

There are two clocks to set. Set the system clock first using the "date" command. For example to set the date to Monday, July 15th, 3:40 PM, 2002, you would type:

date 071515402002

PLEASE NOTE: The system clock is set in 24 hour time.

Next you can easily set the hardware clock by typing;

hwclock --systohc

This sets the system clock time to the hardware clock.
