Set timeZone UTC

[rom]

Since it seems it is not possible to convert to UTC time zone, I thought of putting a C++ method in a .mqh file. But apparently there is a compilation problem. Can anyone give me some help?

    #include <iostream>
    #include <ctime>
    #include <string>

    std::string now()
    {
      std::time_t now= std::time(0);
      std::tm* now_tm= std::gmtime(&now);
      char buf[42];
      std::strftime(buf, 42, "%Y%m%d %X", now_tm);
      return buf;
    }}

In the tester ?

The language is called "MQL". It is not called "C++". Just because MQL is based on C/C++, does not mean that you can use pure C++ code.

If you wan to convert or use zone based time functions, then use the MQL functions for it — Documentation on MQL5: Date and Time

Please note that some of these functions are not supported in the Strategy Tester.

Function	Action
TimeCurrent	Returns the last known server time (time of the last quote receipt) in the datetime format
TimeTradeServer	Returns the current calculation time of the trade server
TimeLocal	Returns the local computer time in datetime format
TimeGMT	Returns GMT in datetime format with the Daylight Saving Time by local time of the computer, where the client terminal is running
TimeDaylightSavings	Returns the sign of Daylight Saving Time switch
TimeGMTOffset	Returns the current difference between GMT time and the local computer time in seconds, taking into account DST switch
TimeToStruct	Converts a datetime value into a variable of MqlDateTime structure type
StructToTime	Converts a variable of MqlDateTime structure type into a datetime value

Hi Lorentzos, thank you for your interest! I don't use tester. In real time, I would like to print such an output "14/12/2022 14:12:38.207", but I need to set the UTC time zone.

Then they have such a provision already

TimeGMT()

It returns the local time , and , in mt5 if you want the estimated server time (of the broker) they have also provided 

TimeTradeServer()

Which does not stop on friday unlike 

TimeCurrent()

In Mt4 some ninja stuff must be done to find the live broker time .

you can detect even in the tester GMT (=UTC) as well as the time in EU and USA and then you can use these time stamps instead of TimeCurrent():

void OnTick() {
...   
   tC = TimeCurrent();
   checkTimeOffset( tC );
   tGMT  = tC + OffsetBroker.actOffset;   // GMT
   tNY   = tGMT - (NYShift+DST_USD);      // time in New York
   tLon  = tGMT - (LondonShift+DST_EUR);  // time in London
   tEU   = tGMT - (FfmShift+DST_EUR);     // time in FFm
...

Excellent work @Carl Schreiber 👏 👏
