Deleting a Group: To remove a group, use the command userdel –g <groupName>.

In addition, you can permit this user to access a particular service by typing -g followed by the user

\> useradd –g telnetd xxxx
user xxxx is existent
group telnetd is existent

Adjusting System Time and RTC Time
The DA-660 computer has two time settings, the system time (or CPU clock) and the RTC (Real
Time Clock) time. The system time regulates the execution of instructions and the RTC keeps
track of the time even when the computer is turned off. RTC time runs on a special battery that is
not connected to the normal power supply. Do not confuse a computer's real-time clock with its
CPU clock.
Setting the System Time Manually: Use the date, and time commands to query the current
system date/time or to set a new system date/time.
