Good day to everyone.
I just bought an 3G/GPRS shield so I can send sms, mails, GPS position... I search in the internet how to ask for date (day and hour) cause I want to sen the date in the sms.
In every web I found they said that the command is:
"AT+CCLK"
And this command should return me something like this:
"+CCLK: yy/mm/dd hh:mm:ss"
The problem is that i don't know how to use it. I try in different ways with out success. It could be something like this??
I tried to put that in the final part of my code (where I chose the data to send in the sms) but I receive "AT+CCLK" in my phone, not the hour...Thanks for your time again Paul...
I write the Serial.print("AT+CCLK"); in "void loop2" but I don´t get the hour. With Serial.print("AT+CMGS=""); I send the sms to a phone number whit out problem but with AT+CCLK I can´t get what I want...
This is the code (you help me with it in another topic):

char phone_number[]="*********"; // ********* numero que recibirá el sms

}
}
I read some manual on the net before post anything in the forum but any of them solve my problem. Maybe it tooks too much time to receive signal grom the GPS... Right now i'm trying to get the date with a DSL1307.
Thanks for your answer.
