Option 4: To encode the offset between universal time and local time in steps of 15 minutes.
Explanation: The timezone part of the Time Zone and Time information element is used to encode the offset between universal time (UTC) and local time, allowing for accurate time zone adjustments. This is crucial for ensuring that mobile devices display the correct local time based on their geographical location.
