Time Synchronisation
Our know-how: transmitting accurate, consistent time data
Bodet has been designing and manufacturing Time Synchronisation Systems all delivering reliable and accurate time to different types of equipment. Our Time Synchronisation Systems are widely known and trusted in the education, industrial, airport, railway and healthcare sectors.
Time synchronisation: guaranteeing reliable, precise time
The principal advantage of radio synchronisation is to ensure the receiver’s accuracy and make sure that it receives time changeovers automatically.
All over the world, time synchronisation can be ensured via a network of 24 satellites that are part of a GPS system. The GNSS antenna receives a message every second (time + date), decodes it and sends it to the Master Clock. The timer server or the primary clock receiving the UTC message (GMT) must be configurable to adapt UTC time to local time (time difference and introduction of Summer/Winter time changeover for the country if necessary). The receiver clocks’ time settings are fully automatic.
Our clocks are also available with ALS 162 (France), DCF (Germany) and MSF (United Kingdom) radio synchronisation.
Our receiving antennas
Bodet offers a range of receiving antennas for time synchronisation of Master Clocks and time servers. We offer radio (DCF, ALS 162) and GNSS (GPS, Galileo, GLONASS, BeiDou) antennas.
Why do you need a Time Distribution System?
Time distribution consists of synchronising a network of clocks over one or more buildings using a Master Clock. For over 40 years, Bodet has designed different Time Distribution Systems guaranteeing a display that is reliable, accurate and identical across all your clocks.
- Savings on starting up the clocks.
- Reduction in maintenance costs.
- Increased productivity.
- Accurate and reliable time display over all the clocks.
- Automatic update of Summer/Winter time changeovers.
Our time distribution technologies
DHF Wireless Clock System
Synchronisation of a network of clocks in one or more buildings without connecting the clocks with cables.
The slave clocks capture the time message and are synchronised automatically. The signal has a range of around 100 to 200 metres.
Major savings can be made with installation, allowing great freedom of location.
Wired Impulse Time Distribution
Electrical impulses sent out every minute to slave clocks by the Master Clock through a wired connection.
Power reserve on the master clock to reset the slave clocks automatically in case of a power cut.
The most economical system for small Time Distribution Systems.
Wired Coded Time Distribution
Transmission of a complete time message (time and date) over a two-wire line.
Standalone operation of the slave clocks for 1 hour if the signal is disconnected.
The system is ideally-suited to digital clock networks.
Wired Computer Network
Time server synchronisation for clocks connected to the IT network.
Computer network time distribution is a standardised solution used to synchronise an unlimited number of clocks using two communication modes:
- NTP/Eth, wired
- NTP/Wi-Fi, wireless
This time synchronisation mode can also be used to supervise the clocks.
The UTC as international time reference
Formerly known as GMT, the UTC (Coordinated Universal Time) has been first introduced in 1960 by the International Radio Consultative Committee.
This time standard defines all time zones used worldwide and regulates clocks and time. It is based on the Earth’s rotation and atomic clocks, making it an accurate and reliable time standard.
UTC makes international communication, navigation, scientific research and commerce easier.
Bodet Time master clocks and time servers synchronise with UTC and distribute this time information to different devices.
Master Clock or Time Server?
- SIGMA Master Clocks control a network of slave clocks. They provide reliable time data in a Clock System and enable programming of analogue clocks</spantyle=>, digital LCD clocks, digital LED clocks and Bell Systems.
- NETSILON Time Servers transmit highly accurate and consistent time data to different types of equipment (computers, clocks, relays, etc.) via the Network Time Protocol (NTP).
Clocks supervision
Monitored time distribution operates with any SNMP compatible software installed on a computer or a server. Monitored time distribution is a system for remotely configuring, tracking the status of and receiving alerts from all clocks connected via your IT network.
This makes it possible to monitor clock operation from a central point and be informed of any incidents with the clocks on the network, which can be installed across one or more sites:
- This provides the functional status of supervised clocks in real time.
- It is possible to receive alerts or information notifications from all Bodet’s supervised clocks.
Time management monitoring also saves costs on clock maintenance due to reducing technician workload. Very simple to use, it is a major asset when monitoring a large number of clocks, especially those spread across several sites.
