Question: Why do you need your own time server although there are time servers available on the internet?
Answer: In principle it is possible to synchronize your computers with time servers on the internet.

However, a lot of our customers rely on their own time server in their network environment for security and/or maintainability reasons:

  • Particularly in the case of our LANTIME you or a responsible person can be notified by mail or SNMP trap if there is a malfunction in your time synchronisation.
  • The clients on the network do not depend on an active internet connection.
  • The clients on the network do not depend on the availability of an external time server.
  • A test of other freely available time servers reported that many NTP servers distributed a significantly wrong time, although they were classified as stratum-1 time servers. This is the responsibility of the server's administrators.
  • If an internet connection is working properly then NTP can determine and account for the packet transmission delays quite reliable. However, if the internet connection is at its capacity limit, time synchronization can be significantly degraded due to high dispersion in packet transmission delays. Reasons for this may be hacker attacks, which must not address your own network, or new viruses causing a huge flood of emails, like it has already happened in the past.
  • An own time server can not easily be compromised out of the internet.
Question: What's this DCF77 stuff?
Answer: DCF77 is a 77.5 KHz radio signal which is the German equivalent of the WWVB 60 KHz timing reference that NIST (National Institute of Standards and Technology) transmits in the United States. The transmitted frequencies and signals of DCF77 are derived from the atomic clocks of PTB (Physikalisch-Technische Bundesanstalt) - the highest technical authority of the Federal Republic of Germany for the field of metrology and physical safety engineering in Germany.

The signal from DCF77 can be received throughout most of Europe - unfortunately, it is not a signal that is applicable to the United States. GPS is the choice for radio reception of precise time in the United States.
