The original GSM spec did not have automatic time as part of the
standard. Later something called NITZ (Network Initiated Time Zone)
was developed so that if your handset supports it (all new Nokias and
most Ericsson handsets and likely other manufacturers as well.) All
the big US networks (cingular & T-Mobile) have NITZ throughout their
networks. Rogers in Canada does (I believe.) Fido in Canada (the
last time I went there in March) does not. Its network and handset
dependant. CDMA handsets on the other hand all have automatic time
adjustment. Its part of the spec for CDMA.
