WLAN - How to NTP time Server

[Jordy101091]

HI all,

Since I have solved together with the matrix team my problem to get my wiz610wi to work, I was wondering for my next step to use a NTP server to provide the time and date for my system.
My question is how do I connect to a NTP time server and how do I receive the correct information.

Regard, Jordy

HI Jordy

I am not at home at the moment have a look on Microsoft site there is quite a bit of info on how to use there time server

Think the address it time.Microsoft.com

Or look for Kb262680

Hi Jordy,

Here is some example code from microchip forums

#include <time.h>

void RtcWriteTime(time_t t){
// write t (seconds since 1970) to rtc
UINT8 buf[7];
struct tm *pTimeStruct; // pointer to where to build rtc values
pTimeStruct=localtime(&t); // fill the structure with t values
buf[0]=DecByteToSwappedBcd(pTimeStruct->tm_year-100); // save year converting 2000 (saved as 100) to 0
buf[1]=DecByteToSwappedBcd(pTimeStruct->tm_mon+1); // save month converting 0..11 to 1..12
buf[2]=DecByteToSwappedBcd(pTimeStruct->tm_mday); // save day of month
buf[3]=DecByteToSwappedBcd(pTimeStruct->tm_wday); // save day of week (0-6)
buf[4]=DecByteToSwappedBcd(pTimeStruct->tm_hour); // save hour of day
buf[5]=DecByteToSwappedBcd(pTimeStruct->tm_min); // save minute
buf[6]=DecByteToSwappedBcd(pTimeStruct->tm_sec); // save seconds
RtcWriteCommand(2,buf,7);
}

time_t RtcReadTime(void){
// reads the time from the RTC and converts it to a time_t (seconds since 1970).
//struct tm TimeStruct; // put rtc values here
struct tm TimeStruct; // Build time here
UINT8 buf[7]; // get 7 bytes of rtc data here
time_t result;
RtcReadCommand(2,buf,7); // send rtc command 2 and read back 7 bytes
TimeStruct.tm_sec=SwappedBcdToDec(buf[6]); // set seconds
TimeStruct.tm_min=SwappedBcdToDec(buf[5]); // minutes
TimeStruct.tm_hour=SwappedBcdToDec(0xfc & buf[4]); // hours - mask out am/pm and undefined bit
TimeStruct.tm_mday=SwappedBcdToDec(buf[2]); // day of month
TimeStruct.tm_mon=SwappedBcdToDec(buf[1])-1; // month (convert 1-12 in rtc to 0-11 in TimeStruct)
TimeStruct.tm_year=SwappedBcdToDec(buf[0])+100; // convert years since 2000 in rtc to years since 1900 in TimeStruct
TimeStruct.tm_yday=0; // not used, but make valid
TimeStruct.tm_isdst=0;
TimeStruct.tm_zone=0;
result=mktime(&TimeStruct); // convert to time_t (seconds since 1970)
return(result);
}


forum post is here

I havent had chance to have a go with this code , it's on this of things to do
