This has nothing to do with summer time. ntp delivers UTC. That is it. It has no idea of what summer time, winter time, time zones are nor does it care. It delivers UTC time. All of the interpretation of the time into things like timezones, summer time, etc are done locally by your computer and your operating system. Many use a set of files called timezone files (tzdata) to look up what the relation between time at your location and UTC is. When politicians decide to change those relations, (eg by abolishing summer time) new tzdata files are issued which need to be installed on your system. You do not tell us what your operating system is etc. Note tht some operating systems leave it up to you to insititute changes (like your wrist watch which you have to keep resetting when timezones/summer times/... change)
So your problem has nothing to do with NTP. It is a problem within the device itself.
