3.7.6. AT+CTZU - Automatic Time Zone Update
Set command enables/disables the automatic time zone update via NITZ.
AT+CTZU=<onoff>
Parameter:
enables/disables the automatic time zone update via NITZ
The command +CTZU is the ETSI standard equivalent of Telit custom command #NITZ
(for the date and time update functionality).
Despite of the name, the command +CTZU enables automatic update of the date and
time set by +CCLK command (not only time zone). This happens when a Network Identity
and Time Zone (NITZ) message is sent by the network.
If the automatic date and time update functionality has been enabled by +CTZU or #NITZ
(or both), NITZ message will cause a date and time update.
AT+CTZU?
Read command reports the current setting of <onoff> in the format:
+CTZU: <onoff>
AT+CTZU=?
Test command returns the supported values of parameter <onoff>.
