NTP Server - ideal for time synchronization of any systems in networks

Little Time Server LTS

LTS is a real powerful NTP time server, small in price and dimensions. It can be used almost everywhere to synchronize computer systems with exact time over NTP. Synchronized with DCF 77 or GPS time signal receivers to the correct time, allows the worldwide use of the LTS as a precise time reference. The LTS can be operated either by the serial interface or via the network (LAN).
