name: NITZ
full_form: Network Identity and Time Zone
context: The purpose of the timezone part of this information element is to encode the offset between universal time and local time in steps of 15 minutes. The purpose of the time part of this information element is to encode the universal time at which this information element may have been sent by the network. The Time Zone and Time information element is coded as shown in figure 10.5.84/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ]  and table 10.5.97/3GPP TS 24.008[ Mobile radio interface Layer 3 specification; Core network protocols; Stage 3 ] . The Time Zone and Time is a type 3 information element with a length of 8 octets.

This may result in incorrect time settings in the mobile.
description: The Network Identity and Time Zone (NITZ) is a type of information element used in the mobile radio interface layer 3 specification, as defined in 3GPP TS 24.008. It encodes the offset between universal time and local time in steps of 15 minutes, along with the universal time at which this information element may have been sent by the network. The NITZ is an essential component for ensuring accurate time settings and synchronization across mobile devices and the core network.
explanation: NITZ is classified as a Message because it represents a specific signaling data exchanged between the network and mobile stations, containing critical timing information necessary for maintaining synchronized operations within the telecommunication system.
