 Periodical query is based on either of the two timekeeping modes: network timekeeping or
local timekeeping. If network timekeeping is unavailable, local timekeeping is used. Local
timekeeping may not be accurate.
 Local timekeeping is affected by AT+CCLK command. Upon a power-off event, the CCLK
value changes to 1980. After you choose to use local timekeeping and change the CCLK
value, the query operation cannot be carried out at the correct time.
