Question: What is the purpose of the Time Zone information element in the mobile radio interface layer 3 specification?
Option 1: To encode the offset between universal time and local time in steps of 30 minutes.
Option 2: To encode the offset between universal time and local time in steps of 15 minutes.
Option 3: To encode the offset between UTC and local time in steps of 60 minutes.
Option 4: To encode the offset between GMT and local time in steps of 1 hour.
Explanation: The Time Zone information element is used to encode the offset between universal time (UTC) and local time in steps of 15 minutes, as specified in the mobile radio interface layer 3 specification. This allows for accurate representation of time zones with offsets that are not whole hours.
