PresenTense Time Server is a multi protocol time server which synchronizes itself with any true time source and then acts as a
server for all network clients. It is easy to set up but has powerful configuration settings for networks which require a high degree
of accuracy. This means you can use PresenTense Server to synchronize your PC to a primary time source such as an atomic clock on the
internet and offer time services to clients on your local area network. PresenTense server also allows synchronization to GPS receivers via RS-232 and the NMEA 0183 protocol. PresenTense Time Server ships with
drivers for many reference clocks including Spectracom and Hopf. If you need an accurate, inexpensive and reliable time server, read

PresenTense Time Server operates three server components concurrently on the ports shown below :
This feature enables you to operate time clients on your network using different time protocols simultaneously depending on your
requirements for accuracy. The latest version of our NTP4 plug-in for PresenTense Time Server ships free of charge with all
PresenTense Time Server software.
PresenTense Time Server features include :
Multi Protocol Support
When operating as a secondary time server, PresenTense Time Server can synchronize to primary, network time servers of the following
protocol families :
GPS Receiver Support
When operating as a primary time server, PresenTense Time Server can synchronize to GPS receivers via the PC's serial port and the
NMEA 0183 protocol. In order to be compatible with PresenTense Time Server, GPS receivers must emit the
GPRMC NMEA sentence (recommended minimum coordinates) at one or two second intervals. Special support is
included for the Garmin GPS 2 Plus and the Garmin 38 hand held GPS receivers. You may use either PresenTense Time Server's native GPS
support or the GPS support furnished by the NTP4 plugin's reference clock support.
Free Run Support
PresenTense Time Server automatically compensates for local system clock drift when operating in NTP or SNTP mode. This
ensures maximum clock accuracy when free-running in the event of loss of connectivity to the reference time source.
The
National Emergency Number Association (NENA) identifies time keeping requirements for Public
Safety Answering Points (PSAP) such as 911 call centers. These requirements include
continuous accuracy of 100 milliseconds to UTC when locked to the reference time source and a maximum clock drift or error
accumulation of one second pay day when the system must "free run". See also PresenTense NTP
Auditor.
Redundancy
An automatic fail-over mechanism switches to a redundant network time source if the primary time source becomes unavailable (only
available when synchronizing to a primary network time server).
Email Alarm Action
PresenTense Time Server can notify you by email if the time source becomes unavailable or critical errors are encountered during
operation. All types of SMTP AUTH are supported including NTLM, LOGIN, PLAIN, NONE and CRAM-MD5.
SysLog server support
PresenTense Time Server can send messages to a local or remote SysLog server. A text based local copy or messages can be generated in
addition to sending to the network based SysLog server.
System Service
PresenTense Time Server operates as a true system service - invisibly in the background. Configuration changes are made via the
PresenTense Time Server applet in the system control panel.
Highly Customizable
PresenTense Time Server features some of the most advanced configuration options on the market today. Some are:
SNTP time engine can be set to serve local time instead of GST/UTC
Selective binding. You choose which time services to make available on which interfaces.
Advanced logging for problem solving.
Extreme fault tolerance. COM ports can be set to poll continuously until a GPS clock comes back on-line.
Security
Initial setup and later configuration via the control panel require administrator privileges. This minimizes the risk of tampering
with system parameters by unauthorized users.
Remote Monitoring and Administration
PresenTense Time Server may be administered fully by remote and monitored over the network to ensure accurate time keeping. Please
check www.bytefusion.com for availability of monitoring software.
Advanced Statistical Filters
Advanced statistical filters ensure that erroneous measurements are discarded, thus
avoiding erratic system clock behavior.
Time Zone Specific Reference Clock Selection
PresenTense Time Server automatically selects the most suitable primary reference clock server, based on your time zone configuration
and geographic location.
