Hello,
I am trying to figure out a way to automatically identify the GMT without asking the user for a parameter offset value. I see EA's on the market that can automatically determine the GMT, but does anyone know how to code that?

Thanks!

I use this code. TimeUTC() gives you GMT.

Inserted Code

#import "kernel32.dll"
int  GetTimeZoneInformation(int& TZInfoArray[]);
#import

#define TIME_ZONE_ID_UNKNOWN   0
#define TIME_ZONE_ID_STANDARD  1
#define TIME_ZONE_ID_DAYLIGHT  2

int TZInfoArray[43];

datetime TimeUTC() 
   {
return( TimeLocal() - TimeZone() * 60 );
   }

int TimeZone() 
   {
int ret = GetTimeZoneInformation(TZInfoArray);
int bias = TZInfoArray[0];
if (ret == TIME_ZONE_ID_STANDARD) bias+=TZInfoArray[21];
if (ret == TIME_ZONE_ID_DAYLIGHT) bias+=TZInfoArray[42];
return(-bias);
   }
