htpdate: Set time immediate after the synchronization.
$ sudo htpdate -s ${host}
try on your machine
This command is used to synchronize the system time with a remote time server using the utility called htpdate.
Here's the breakdown of the command:
- "sudo" is a command used in Unix-like operating systems to run a command with superuser (administrative) privileges. It allows the user to execute the following command with elevated privileges.
- "htpdate" is a program used to synchronize the system time through HTTP protocol with a remote time server.
- "-s" is an option or flag used with the "htpdate" command. In this case, it stands for "set", indicating that the system time should be set to match the time retrieved from the remote server.
- "${host}" is a placeholder or variable that should be replaced with the desired hostname or IP address of the remote time server. The actual server address should be provided when executing the command.
By running this command with appropriate privileges and specifying a remote time server, the system's time will be synchronized based on the time information received from the server.
