TimeTools digital wall clocks synchronise to an internet or intranet based NTP or SNTP time server. The NTP time server obtains accurate time from a radio or GPS external timing reference. Timing information is then distributed around an ethernet network to the digital wall clocks. Utilising this method of time distribution reduces product costs and installation, since the need for complex and expensive timing equipment is minimized or even eliminated.
