FS#548 - firewall3: Timezone problems, UTC used always despite UTC Time not checked

It seems the commint has entered into 17.01.2. I have tested it and now it works. Even --kerneltz must be removed from extra args because otherwise the rule fails as --kerneltz is setup twice.

I have tested also checking time in UTC and works as expected.

Thanks jow.
