ntpdate
ntpdate uses Network Time Protocol to set computer clocks
Network Time Protocol, or NTP, is used to set the clocks on computers in a network by synchronizing them over the Internet or local network or via another time source. ntpdate is a simple NTP client that communicates with one or more NTP servers to request accurate time and then set a system's clock. In order to achieve a more accurate reading, ntpdate polls several NTP sources and selects the best time using an algorithm. ntpdate can be run manually when needed to set the host clock, or it can be set to run at bootup or at regular intervals. The key to achieving the highest level of accuracy with ntpdate, however, is to derive time from the most accurate source, and Symmetricom provides enterprises with the solutions to do that.
Symmetricom network time servers delivers accurate time for an ntpdate client
Symmetricom's time servers are a Next Generation-ready servers that can respond to an ntpdate request for time with a highly accurate reading. These time servers use an integrated GPS receiver to track and derive time from the atomic clocks on GPS satellites, and thus offers one of the most accurate solutions for network timekeeping. In the event that communication with a GPS satellite is lost, the time server can either revert to Stratum 2 mode and retrieve time from another source, or it can be upgraded to included a Rubidium oscillator that keeps accurate time to within 6 microseconds per day while the GPS signal is reestablished. These time servers also allow organizations to respond to an ntpdate task without needing to leave a port open (as is necessary for other time sources that use the Internet for synchronization.) This mitigates security risks such as spoofing, hackers and malicious tampering that may occur when a port is left open. Symmetricom time servers are extremely easy to use. Their front panel is designed to bring it online with a few keystrokes or DHCP, and administrators can configure and control it through intuitive interfaces and using a standard web browser. They have multiple NTP ports, so they can adapt to different network topologies, and they have the bandwidth to deliver time to hundreds of thousands of clients and ntpdate requests.
Why delivering the most accurate time for an ntpdate request is important
When network time is not accurate, data may be lost, processes can fail, operations can break down, security can be breached and credibility of the organization is on the line. Luckily, Symmetricom's network time servers offers an easy and affordable solution that can protect the organization from these risks.
