22.0423GPPNetwork Identity and TimeZone (NITZ)Service descriptionStage 1TS
6.1 Transfer of NITZ information
Network name, time, DST and timezone information can be transferred from the serving PLMN to the MS:
1) Upon registering on the network.
2) When the MS geographically relocates to a different Local Time Zone.
3) When the network changes its Local Time Zone, e.g. between summer and winter time.
4) When the network changes its identity.
5) At any time during a signalling connection with mobile station.
Transfer of relevant information shall not unduly consume scarce network resources.
6.2 Use of NITZ information
Relevant information shall be presented to the MS user at the earliest opportunity.
It is expected that the MS will display the most up to date information transferred to it.
Switching off the MS should not cause the updated name of the network(s) to be deleted.
Removal of the SIM/USIM should not cause the updated name of the network(s) to be deleted.
However, the number of different network identities retained in the ME is a manufacturer issue.
Usage of time information in MS is a ME manufacturer issue. For example, time information can be utilised to time stamp transactions for logging purposes.
