Linkedin error

Hi I'm trying to configure the linkedin zimlet on Zimbra 7 and am getting the following error:

oauth_problem=timestamp_refused&oauth_acceptable_t imestamps=1298415953%2B-300

Any ideas on what could be wrong?

Hi aspiro,

The time stamp you send to Linkedin from Zimbra might be expired.
There are some possible causes depends on where and when the timestamp
is created.
But the most possible one is your zimbra server's time stamp.
Maybe you better start to check it first.
