How to make WCF service server-client time difference independent?

Question

System.ServiceModel.Security.MessageSecurityException: An unsecured or inco

There can be multiple reasons for this error, the common one is related to server not authenticating client for variosu reasons (maybe not on the same domain). To determine the exact reasons turn on wcf trace and see what errors it shows in red. What you're looking for is the inenr exception which is a little hidden in the trace UI, it is in the right side in the middle down the tree.

Note skew can only be defined on a custom binding. Since you use WSHttpBinding you need to convert it to a custom binding which can be easily be done online via WCF binding converter.
