Solution for Server Certificate Security Not Valid Problem

Recently I came through a problem after installing new windows in computer. After installing Google Chrome and Mozilla Firefox while browsing Gmail, Yahoo! or Facebook a error appeared saying "server security certificate is not yet valid" after we click on "continue anyway" same problem continues. Here I have got solution for this problem. Just need to follow few instructions for this.

Actually this problem occurs due to incorrect "date and time setting" It can be solved by changing incorrect date and time. Due to difference of time between computer and certificate provided by server this error occurs.

Change Date and Time by following instruction:

• Go to "Start Menu" and Click on "Control Panel".
• Click on "Date and Time".
• Click on "Change date and time".
• Set date and time.
• Click on OK.

You can also automatically update time from internet:

• After you will open date and time settings in control panel, go to internet time tab.
• Click on change settings.
• Tick on the synchronize with an internet time server.
• Choose a server you want to update time from.
• Then click on update now. You will see time and date will cahnge.
• Click on OK.

After setting up correct date and time the error will disappear and you can browse easily without inconvenience.
