CRM Online 2011 connect using sdks

Hi,

Cann't we connect to CRM Online2011 using sdks? I tried to connect using the sdk's sample but it gave the following error:

The security timestamp is stale because its expiration time ('2011-09-05T11:24:24.000Z') is in the past. Current time is '2011-09-05T22:48:04.267Z' and allowed clock skew is '00:05:00'.

Please advise.
