Strange, so indeed you have the Date fix, so it should correctly detect 
timestamps "in the future".

So, the only explanation for the check still passing seems to revolve 
around us assuming a different *server time* than what OpenSIPS actually 
reads.

Some ideas to gather more info on the problem:

* first of all, check for any "silly" reasons for the error such as, but 
not limited to:
   - upgrading the OpenSIPS package to 3.4.2+, but forgetting to restart 
the instance, which is still running 3.4.1
   - an extra line somewhere "lower" in the config file by mistake, 
resembling modparam("stir_shaken", "verify_date_freshness", 7200) or similar
* double-check for any unwanted "TZ" environment variable being set as 
OpenSIPS starts (ideally, this var is not set)
* double-check the system's timezone is really CET, using:

$ date +%s # to match what UNIX timestamp OpenSIPS is pulling from the 
OS as well
$ cat /etc/timezone

Finally, if you still can't get it to reject that Date header, please 
open up a bug report on GitHub with some examples on and I'll take a 
closer look.
