> Some of token expire exception is triggered by wrong time settings on cluster
> nodes, but the current exception message does not explicitly address that. It
> would be helpful to add some message explicitly pointing out that this
> exception could be caused by machines out of sync in time, or even wrong time
> zone settings.
