Certificate Revocation List

I tried to check the Certificate Revocation List, but it seems it’s not to be a valid one.
Will that not be supported anymore ?

Can you please clarify which CRL this is from and how you got that data?

Sorry my fault, We are in 2012.
So it should be valid. But the Point is when i check the Certificate we got the Message :
The Certificate Revocation List needed to verify the signing certificate is either unavailable or it has expired.
The information are found at

Is the time and date on your computer correct?

Yes it is, i use NTP from Internet
