Digital Time Servers


Why does our organization need a dedicated Network Time Server?

In one word:  Security.
In two words: Consistency & Reliability.

A Digital Network Time Server provides time from your organization’s own dedicated GPS Antenna.  It is not only reliable but also provides complete system security. The system is a closed circuit and is not open to any outside influences.  Compare our system to using a time reference from an open internet server – the time reference is coming from someone else’s time server across a public internet.  This not only opens a door into your network, but is also inconsistent and easily hijacked. If you are concerned about a reliable, consistent and secure time reference for your critical applications, the Mobatime Digital Network Time Server is made for you and your peace of mind.

A MOBATIME network time server will:

  • Use a dedicated GPS antenna to receive time
  • Make your network secure
  • Improve accuracy of your time services
  • Increase flexibility
  • Provide a user-friendly interface

What is a time server

A time server is a server computer that reads the actual time from a reference clock and distributes this information to its clients using a computer network. The time server may be a local network time server or an internet time server.  The most important and widely used protocol for distributing and synchronising time over the internet is the Network Time Protocol (NTP), which Mobatime uses.

The time reference used by a time server could be from another time server on the network or the internet, a connected radio clock or an atomic clock. The most common true time source is a GPS or GPS master clock. Time servers are sometimes multi-purpose network servers, dedicated network servers, or dedicated devices. Mobatime is a redundant, dedicated time server whose only purpose is to provide accurate time.

The term “stratum” is used to label the closeness to a central or high quality time server. The stratum indicates the place of a particular time server in a hierarchy of servers. The scale is 0 to 14 where 0 is the most accurate and likely a highly specialized physical hardware device. Some time clients will reject a time update from a server whose stratum is too high, and most will prefer low strata time sources to higher ones. This can be a pitfall for administrators setting up an in-house time server with no true time source. Mobatime digital network time servers uses a time reference directly from Mobatime and typically has a strata of 1.
