Linux 时间在双系统中的应用(linux时间双系统)
Nowadays, many computer users prefer to use two kinds of system at the same time, commonly known as dual system. This requires a very important factor ——— Time. Of course, the time on the dual system needs to be kept the same. In this paper, I will mainly introduce the application of time in dual system under Linux.
Linux is an open source operating system that includes core components such as the Linux kernel. Now most of the dual system use Linux as its own system, so the time management in dual system is especially important under Linux. Time is stored in the kernel as a Unix time, which is a continuous number from the start time, defined as the Unix time_t type, which is different from the human readable time format.
Time sync under Linux is mainly managed by the ntpd (A Network Time Protocol Server) service, which is ntp time synchronization service that synchronizes time with other servers. To realize time synchronization, you must first install ntpd on the machine and make sure it is running.
If we want to customize the time synchronization between the dual system, we can take the following steps:
1. First, set the NTP server. This can be set in the configuration file of /etc/ntp.conf
2. After the setting is complete, restart the NTP service
# systemctl restart ntpd
# systemclt enable ntpd # Optional if you need to start when the kernel starts
3. Finally, run NTP client commands to synchronize time with specified NTP server.
# ntpq -p
Therefore, it can be said that time is particularly important in the dual system. The settings and synchronization of NTP service can ensure the accurate time of dual system. This article has simply introduced the application scenario of time in Linux dual system, which provides a reference for Linux users in maintaining the dual system.
