Section: 8.2.13.5 Universal time and local time zone
Content: This IE may be sent by the network. The UE should assume that this time zone applies to the tracking area the UE is currently in, and also applies to the tracking area list if available in the UE. The UE shall not assume that the time information is accurate. NOTE: The time information can be inaccurate, especially when the TAI list includes tracking areas belonging to different time zones. If the local time zone has been adjusted for daylight saving time, the network shall indicate this by including the Network daylight saving time IE.
