A stratum 1 time server is a device which obtains very precise time from an external time reference. Timing references such as GPS or national radio time and frequency broadcasts provides very accurate time. The device uses the received timing information to provide an accurate source of time to other equipment, generally computing equipment over a network.
Many computer network timing protocols, such as NTP, are hierarchical. They operate within a pyramid structure, where each level obtains time from the level above. At the top of the tree is a stratum 1 device which obtains time from an external hardware reference. Each level in the hierarchy is slightly less accurate than the one above. External hardware clocks are often referred to as stratum 0 devices.

TimeTools has a comprehensive range of computer and network time synchronisation solutions utilising GPS and radio technologies. Solutions range from RS232 serial and USB devices that synchronise time on a single PC to dedicated network time servers that can provide accurate time to thousands of network time clients. We also provide a comprehensive range of ethernet network, NTP synchronised, digital and analog wall clocks that continuously display accurate synchronised time.
