Devices that support more than one entry
Here we recommend the following server entries for redundancy reasons:
- ntp1.zih.tu-dresden.de
- ntp2.zih.tu-dresden.de
Devices that allow only one entry

Setting incorrectly functioning secondary clocks
Do not attempt to correct the clocks! The causes of malfunctions in the network clocks are often construction underway (conduction abnormalities), or dirt. An arbitrary "correction" worsens the situation due to the structure of the network clocks or destroys the electro mechanical movement. Therefore please consult the service desk via email (servicedesk@tu-dresden.de) if a clock is not working correctly. We will take care of it as soon as possible.
The TU Dresden is also not responsible for battery-powered (radio) clocks. If you want to install such a clock you are also responsible for faults, battery replacement and conversion during summer / winter time.
