NTP is Network Time Protocol, which is a protocol used to synchronize each computer in the network.
Time zone and time consistency is very important for cloud server ECS, sometimes directly affecting the results of the task execution. For example, when you update your database or analyze log, the time order has a great impact on the results. To avoid problems such as logical confusion and network request errors when running business on ECS instances, you need to unify the time zone settings of the relevant ECS instance. In addition, you can also synchronize local time of ECS instances in each network through NTP services.
