How to Synchronize Date and Time From Another System

1. Become superuser or assume an equivalent role.

   Roles contain authorizations and privileged commands. For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services.

2. Reset the date and time to synchronize with another system, by using the rdate command.

   # rdate another-system

   another-system

   Name of the another system

3. Verify that you have reset your system's date correctly by using the date command.

   The output should show a date and time that matches that of the other system.
