Note that this usually reads the module internal clock, NOT the network time. You need to configure the modem to sync its RTC to the network with a separate command. Off the top of my head it's AT+NITZ or AT#NITZ for Telit models at least.
I'm pretty sure the time includes the offset already. I can check if you give me a day or two.
Yeah, but the module doesn't have battery backup, so it either reads time starting at the epoch or network time once it's synced, it's easy enough to figure out if it's done a sync.
The modules that we're using have a default configuration which has NITZ enabled (they're motorola ones, although telit bought motorola and the latest batch we have got from them are badged as telit).
Quite why they don't explain whether this is GMT or localtime in any of their manuals (or any other manufacturers manuals that I could find) is, well, beyond me....
I think rod has given me the definitive answer with his reply.
