You can't really. They are a vital part of the software. Not only do we use it to see if an Agent is logged in, but we also store a ton of information in the session. You will need to figure out why the time is showing different.
If I were you, I would look at the IIS error logs, PHP error logs, and MySQL error logs to see if there are any related errors when attempting to login. The error Invalid CSRF Token
is pretty generic and doesn't provide us with any helpful information other than you have invalid tokens.
