Motorola G24 用户手册

This command reads and sets the G24 current date, time and time zone.

The Set command sets the date, time 
and time zone of the system clock.

Set Command sets user defined 
system clock values and saves 
them in the NVM memory. 
These saved values are kept 
after power-cycle as well.

The Read command returns the current 
date, time and time zone setting.
By default, <time> will represent the 
network updated time.
If the user has used the Set command 
once, then <time> will represent the 
Set command setting.

If network operator does not 
support System Clock Update 
Message, the initial date, time 
and time zone, displayed by 
CCLK Read Command could 
be invalid (user's responsibility 
to set date, time and time zone 
by CCLK Set Command).

See Execute Command for 
how-to enable back network 
update time.

The Test command returns valid 
parameters for the +CCLK Set 
command.

The Execute command causes system 
clock to be overridden by network 
System Clock value immediately.

CCLK Read command will 
represent the network update 
time after CCLK Execute 
command. This value will be 
represented after power-cycle 
as well.
