Is there a possibility to get current time (UTC preferred) from a

Commands Reference Guide, but only references to "time" are in
context of SMS. Not sure if it depends on the type of modem, but
a possible candidate is the Telit GE863.

In the past we have used NTP over the dataconnection to get time
on our device. But for a new device, I was hoping to skip the added
complexity of using NTP. Mainly to avoid having to set up a dedicated
NTP server or make arrangements with pool.ntp.org or another provider.

I have absolutely no experience in this area but it strikes me as
unlikely. Consider it from a user perspective - you still need to
set the time and date on a GPRS equipped handset.

As for "making arrangements" for NTP - what are you on about?
They're open access servers. Or is there some licensing condition
against "productising" the service? I haven't checked and I'll
admit I don't know for sure.
