These instructions will allow you to set the date and time on the Ultimaker S3 / S5 by logging into the printer and executing commands to set the date and time. This is useful for situations where the local network port 123 has been blocked. 

Disclaimer:
Ultimaker S3 / S5 does not have an internal battery. This means the date and time will be reset to "default" if the machine is powered off or restarted.
It is recommended you allow the machine access to port 123 to properly keep track of date and time.

Please see here for information about network requirements of the Ultimaker S-Line
