Network Time Protocol (NTP) is a protocol that provides a reliable way of transmitting and receiving the time over TCP/IP networks. It has become the de facto standard for synchronizing Internet computers and other networked devices to Universal Coordinated Time (UTC), which is accomplished by having these devices reference a common time source – i.e., an atomic clock or a network time server (a.k.a. an “NTP server”). (NTP is defined in IETF RFC 1305.)
NTP uses port 123, which must be opened on a firewall or router to ensure proper communication with the NTP server.
Simple Network Time Protocol (SNTP) is a simplified version of NTP, which is used in cases where a full implementation of NTP is not required. Because SNTP uses the same packet format as NTP, SNTP clients can utilize NTP servers. (SNTP is defined in RFCs 1361,2030 & 4330.)
SNTP is implemented on the PoE clock. By default, SNTP time synchronization is performed once per hour, which keeps the displayed time within 200 ms of actual time. (For more information on how to configure your clock for an SNTP server see How do I configure my PoE clock for an SNTP Time Server? below)
International Atomic Time is an international time standard derived from 200 atomic clocks in 50 national laboratories from around the world. The readings from these clocks are used to form the standard for Coordinated Universal Time (UTC), which governs global time-keeping.
Spectracom's NetClock 9483 offers a versatile modular design that's fully NENA compliant and tailored especially for Emergency Communication Center applications. And now it has a new Web User Interface that's easier to use and provides intuitive status monitoring with simple set-up.
A key feature of the 9483 is its capability of time-synchronizing multiple separate networks. The modular design provides expansion card slots, one of which is the 3-network port GigE option card providing synchronization for up to (4) networks simultaneously. Cards can be added with the initial order, or in the future as system requirements change and evolve.

PresenTense offers you an alternative to the limited functionality of synchronizing with Microsoft W32Time program. PresenTense, will not only synchronize all of the Windows PCs on the network, but also provides alert notification and a audit trail which is not available from the Microsoft W32Time (Windows Time Service). PresenTense Client and Server software is a has Graphical User Interface (GUI) based program that can provide a primary and back-up time reference for redundancy.
PresenTense Client software synchronizes the PCs to the Time Server and/or another PC on the network that is running the Server software. If the PC can’t reach its Time reference, it can email an alert notification that it can’t be synchronized. PresenTense LAN Time Analyzer is a network time synchronization administrative tool that monitors the time accuracy of all PCs on the network. If a PC exceeds a user-defined accuracy specification, this program can run any exe-based program and can also open a message on the PC’s monitor, alerting to a PC with an error higher than expected and desired
The PresenTense NTP Auditor program provides an audit trail of the PC’s time by comparing the PC’s time to up to three different NTP Time references. This program can provide a continuous print-out for a hard-copy proof that each PC was synchronized at any given moment in time. It also logs this information in a text file sorted automatically by month and day. The time is sampled at set intervals and the error of the PC’s time compared to the reference NTP Time Servers is permanently captured. If the time of the PC is manually set by someone at any time between the scheduled samples, the program automatically triggers an unscheduled sample to permanently log how far off from UTC the PC was manually set and when the event occurred. Once the PC is resynchronized or manually set again, another unscheduled sample occurs again and the time of this occurrence is logged.
If you would like to try Presentense for your network you can obtain a free 30 day evaluation trail by contacting us at Telnet Networks at 800-561-4019. You can download you 30 day free trail here

Government and military networks often utilize the concept of unclassified networks vs classified networks to manage levels of information security. Since a complete "air-gap" around a highly sensitive network is not practical, every data connection is evaluated as a security risk. When it comes to accurate synchronization traceable to time standar...
Problem We Solve Military bases, government facilities, and other fixed-site locations need a way to protect against the threat of signal jamming and spoofing. Because GNSS signals are relatively weak once they reach the surface of the Earth, they can be easily manipulated. Adversaries can turn low-cost SDRs into GPS jammers and spoofers. They then...
