Isn't GMT a time zone (mean solar time at the Royal Observatory in Greenwich) that can differ from UTC up to 0.9 seconds?
So since the RFC specifies GMT it is already up to 0.9 seconds wrong?

Universal Time remains in general use in a modified form as Coordinated Universal Time (UTC), which serves to accommodate the timekeeping differences that arise between atomic time (derived from atomic clocks) and solar time.
