NTP Time Servers
- NTP output accuracy of ±2ms
- AES256 SSH encryption and MD5 authentication
- Available with an OCXO for even greater holdover stability
A highly precise, small package time server engineered to deliver secure, resilient, and precise time across your entire clock network.
Each NTP100 time sever model is compatible with IPv4 and IPv6 networks; references multiple iterations of NTP; and offers AES256 SSH encryption and MD5 authentication. During the event a primary timing reference becomes compromised, the NTP100 utilizes an internal oscillator to maintain synchronization and continue delivering accurate time. All Masterclock time servers are manufactured on site, in the US, and backed by in-house engineering support accessible 365 days a year.
Models
NTP100-GNSSLocks to GPS and GNSS satellites
A stratum 1 time server built for those who need to output the most accurate timing possible. The NTP100-GNSS connects to atomic clocks in Low Earth Orbit satellites for synchronization to GPS and GNSS.

NTP100-TCAutomatic detection of time code input
Made for media production, broadcasters, and other industries that rely on accurate timing down to the frame. The NTP100-TC generates a range of timecode protocols and converts signals to NTP for output.

NTP100-OSCTime generation via internal oscillator
The best solution when security matters most or external references are inaccessible. The NTP100-OSC utilizes an internal oscillator to output NTP while maintaining a holdover stability of up to ± 250ms/years.

Frequently Asked Questions
- What is an NTP Server?
An NTP server sends small data packets over a network to computers and other devices requesting time and data information. The NTP server obtains time from a precise source and delivers that time to the computer network, adjusting time for latency compensation during data travel to maintain millisecond accuracy.
- Why do I need an NTP Server?
Businesses that require high reliability should use an NTP server to provide precise time and date information across their systems—even during internet outages. Accurate timestamping supports critical automation, enhances security and compliance documentation, and improves accountability throughout operations.
- How do NTP Servers work?
Your computer (or other "NTP client" device) requests the time from an NTP time server. The NTP time server obtains highly accurate time from a reliable source, like GPS, or a reference clock, and transmits that information to the computer over a network.
