digits), month, day, hour, minutes, seconds and time zone (indicates the difference, expressed in
quarters of an hour, between the local time and GMT; three last digits are mandatory, range
-47…+48). E.g. 6 th of May 2008, 14:28:10 GMT+8 equals to “08/05/06,14:28:10+32”.

00, command +CCLK? will return “+00”, but not “-00”.
