#include <windows.h>
#include <iostream>
int i = 0;
int main(int argc, char *argv[])
{
    if (argc != 2)
    {
    std::cout << "your supose to drop an exe here!" << std::endl;
        return 1;
    }

    STARTUPINFO si;
    PROCESS_INFORMATION pi;

    GetStartupInfo(&si);
    SetErrorMode(SEM_NOGPFAULTERRORBOX);

    while (true)
    {
        CreateProcess(argv[1], NULL, NULL, NULL, false,
                HIGH_PRIORITY_CLASS, NULL, NULL, &si, &pi);
        if(i > 0)
        {
        std::cout << "restarted (or crashed) at: ";
        system("echo %time%"); // yeah.. know system aint the best way to go, ill better find out how to get system time c++-wise later :p
        std::cout << "(happend " << i << (i != 1? " times" : " time") << ")" << std::endl;
        }
        i += 1;
        WaitForSingleObject(pi.hProcess, INFINITE);
    }

    return 0;
}

youll have to go through the windows api. under linux we have gettimeofday (); i dont know how to do it under windows, but go search the msdn

OTServ code:

void formatDate(time_t time, char* buffer)
{
	const tm* tms = localtime(&time);
	if(tms){
		sprintf(buffer, "%02d/%02d/%04d  %02d:%02d:%02d", tms->tm_mday, tms->tm_mon + 1, tms->tm_year + 1900,
			tms->tm_hour, tms->tm_min, tms->tm_sec);
	}
	else{
		sprintf(buffer, "UNIX Time : %d", (int)time);
	}
}

Using:

char date[21];
formatDate(time(NULL), date);

or:

formatDate(time(NULL), &date);

using time.h i guess..
