„
The command AT+CTZU=1 enables automatic update of the date and time set by AT+CCLK command (not only
time zone). This happens when a Network Identity and Time Zone (NITZ) message is sent by the network. This
command is the ETSI standard equivalent of Telit custom command AT#NITZ=1. If command AT+CTZU=1, or
AT#NITZ=1 (or both) is issued, NITZ message causes a date and time update.
