Introduction - Symmetricom ND-CLK User Manual

INTRODUCTION

The ND-CLK is a network analog clock, with a built-in SNTP (Simple Network Time
Protocol) client. It is designed to display time referenced to either an internal NTP time
server, or one located on the Internet. The ND-CLK contains a stepper motor drive with
advanced microprocessor and electronics to rapidly and automatically synchronize the
hands on the face of the clock to an accurate NTP (Network Time Protocol) time server.
The ND-CLK can be configured to display local time for any time zone worldwide by
enabling time zone offset and automatic DST (Daylight Saving Time) adjustments. This
device allows for maintenance free, reliable, quiet operation.
