Question: What is the format for specifying the time zone in the `<time>` string value for the `+CCLK` command, and what does it represent?
Option 1: ZZZ; represents the time zone's abbreviation (e.g., GMT, EST)
Option 2: +/-XX; represents the difference in quarters of an hour between local time and a fixed offset from UTC
Option 3: XXX; represents the time zone's UTC offset in hours and minutes (e.g., +02:00)
Option 4: +/-XX; represents the difference, expressed in quarters of an hour, between the local time and GMT
Explanation: The correct format for specifying the time zone is indeed +/-XX, where XX represents the difference, expressed in quarters of an hour, between the local time and Greenwich Mean Time (GMT). This allows for precise adjustment to account for various time zones worldwide. For example, a value of +08 would indicate GMT+2 hours, considering each quarter of an hour (e.g., 8 quarters = 2 hours).
