Timestamp from GSM Network

Ok guys,
with gsmAccess(true) it is possible to send (and see on serial port) AT commands; following this step I have tried to send AT+CCLK? right now (2013-07-02 17:00:00) receiving as reply from the modem:
85 2>%13%%10%OK%13%%10%%13%%10%+CCLK: "08/01/01,01:39:15+00"%13%%10%%13%%10%OK%13%%10%

How can be possible that the timestamp that it gives to me is "08/01/01,01:39:15+00"?!?
What's wrong?
