This paper mainly talks about the importance of the financial system in the operation of the time benchmark, and the function of the central clock in the financial system and the role played by the central clock in the process of time synchronization and unification, so as to facilitate the users of the financial system to give some reference to the problem of time synchronization.

The center clock of our company has been put into use in many financial system units, and the time needed to synchronize with the equipment in the financial system has been completed. The financial system is a system of the flow, concentration and distribution of capital. It is an organism consisting of a series of financial intermediaries and financial markets that connect the surplus funds and the shortage of funds. The financial system is mainly linked by three parties. The link information of all the three parties needs to be unified in a whole framework, which forms a special network of financial system and the transmission of network equipment in different subsystems. Therefore, the time synchronization and unification of the financial system actually refers to the time synchronization of the electronic devices in the financial system network links.

The function of the central clock used in time synchronization service in the financial system mainly refers to the establishment of a network clock timing system with the center clock as the standard time base. It provides a high precision clock correction reference standard for all kinds of application devices in the system. It is the time maintenance of the real-time information system between the network links of the financial surplus agencies, the financial intermediaries and the financial markets. Synchronize and control the error of all link network devices and standard time within the allowable range.

At present, the main application models of the master clock in the financial system center are SYN2151 NTP time synchronization server, SYN4505A clock synchronization device and SYN012 timing equipment, which are the three most commonly used devices in the time synchronization of the financial system as the central clock function. They mainly assume the function of the central clock in the time synchronization of the network link equipment in the financial system. After the market test and the time frequency technology development, the equipment has made the best cost performance functional upgrading in the traditional central clock system equipment.

All the central clock used in the link system of the financial system must satisfy the function of integration of time source and NTP network timing, that is, the center clock is the carrier of the time synchronization function, and it bears the function of receiving time source. The standard is to receive the Beidou GPS satellite time signal, at the same time, it will bear the standard time signal received from the satellite, and it will give time through the NTP network. The mode is transmitted to the network equipment in the financial system. All electronic devices in a private network or multiple sub networks can get the time information provided by the center clock according to the agreed NTP protocol, so as to achieve the time synchronization and unification of all the devices in the financial system.

The center clock as the carrier of time synchronization function is the standard time equipment to be provided in the normal operation of the financial system. For the specific application of the central clock in the financial system to the time synchronization service, we can consult our company's business personnel.
