Why do we need a "System of a Single Precise Time" in enterprises?

Question

NTP

Why do enterprises need a "Uniform Precise Time System". For computers, servers, etc. to have a single time on the network, this is understandable. But for what purpose do you need millisecond precision?
I found only this:
- The exact time should be in various event logs when debugging or investigating incidents
- Over time (or in the event of various failures), the system clock can go wrong, which can affect the correct operation of various programs
Why else do we need a single exact time system, and in what area do you need accuracy to milliseconds?

Answer 1

Everywhere, where a lot of different things are done in a unit of time, and if something goes wrong, then a disaster: Russian Railways, Aeroflot, Metro.

Answer 2

In the banking sector, it is extremely important to observe the accuracy of time in the work of the core banking system and credit conveyors in connection with the requirements of the Central Bank and the security services of the banks themselves.

Answer 3

In what areas it is clear why all this is needed there.

Answer 4

The use of an accurate time source allows you to synchronize the start and end points of any process in the network, which is necessary, for example, when charging in accordance with the time of day and the location of the subscriber, when carrying out process control procedures, procedures related to confirming the receipt / transmission of an electronic signature, making transactions , etc.

Answer 5

Devices for recording the exact time are called NTP servers. They are embedded in access control systems (ACS) at enterprises, in ATMs around the world, in various research software. There are also 2 fundamental differences between NTP and SNTP servers, here you can read https://www.komset.ru/informatsiya-o-kompanii/arti... In short, an NTP server is a complex thing (device), SNTP is a lightweight protocol for end users.
