Get time using C++

[TimTDP]

I need to develop software for a gsm modem. Part of the brief is to get the current time.
What commands can I use to use the current date / time?
I am programming in C++

/* localtime example */
#include <stdio.h>
#include <time.h>

int main ()
{
time_t rawtime;
struct tm * timeinfo;

time ( &rawtime );
timeinfo = localtime ( &rawtime );
printf ( "Current local time and date: %s", asctime (timeinfo) );

return 0;
}

Are you trying to get system time or are trying to get the time from the device?

Also what libs are using? eg QT

I am trying to get the system time from the GSM network

I am using a Wavecom Fast Track supreme modem, and it does not have a real time clock

Your looking at NITZ and you need to reference your Wavecoms AT command manual. I've tried to test my E220 but it does not support NITZ. Also most devices only get the time zone from the network and not the actual time. From looking at one of the Wavecom AT comman guides it does seem possible to do it. Wavecom have their own set of commands.

May I ask why you need the network time? If your looking at auditing then rather make use of a data base to insert your SMS and DLRs.
