Time packet

Does anyone know what's the problem with time packet on 5017?

Code:

public static Packet CreateServerTime(this Packet stream, DateTime Time)
       {
           stream.InitWriter();
           stream.Write(0);//type //int
           stream.Write(Time.Year - 1900);//int
           stream.Write(Time.Month - 1);//int
           stream.Write(Time.DayOfYear);//int
           stream.Write(Time.Day);//int
           stream.Write(Time.Hour);//int
           stream.Write(Time.Minute);//int
           stream.Write(Time.Second);//int
           stream.Finalize((ushort)NetPacketTypes._MSG_ServerTime);
           return stream;
       }

5017 don't accept time packet?

Can you provide a hex dump of the finalized packet? Also, what happens when you explicitly cast those time values to 32-bit integers?

Never got time working on 5017 either. Just posting here to get notified

I managed to fix time with a hook. I only posted here maybe someone knew a solution to save some time.

A hook? So you're saying that patch 5017 doesn't support the time packet? Also, that could be a helpful bit of code to post here rather than it dying off with the community. We've lost a lot of collected knowledge from developers just leaving and not documenting anything they've discovered. I could make a client hook snippets section of my wiki if you'd like to contribute.

I dont know if is working or not but i remembered that they use sprintf for this string.

Oh, I see how you did that now. No worries then. If you'd like to share the code, then great, but that one seems simple enough with a hint. Are you sure it doesn't support the time packet though? Do any other 5017 sources implement it maybe?

I dont know if "Time packet" is working or not

Code:

char StrFormat[] = { "[%s] (%03d,%03d) Ping: %04d; Fps: %02d; Time: %02d:%02d, %s" };

Code:

int  my_sprintf(char *buffer, char *format, ...)
{
    va_list args;
    va_start(args, format);

    if(!strcmp(StrFormat,format))
    {

        /*char* ServerName = va_arg(args, PCHAR);
        int x = va_arg(args, int);
        int y = va_arg(args, int);

       //TO DO
       */
    }
    return vsprintf(buffer, format, args);
}

hook msvcrt.dll , function-> sprintf

well.... you can compare just first 10 bytes...

Hm. That seems to be a bit of a naive approach, looking for a value rather than a key, but if it works then it works. I looked into other 5017 sources just to be sure that time packet (packet 1033) really isn't implemented anywhere, but I found one that does implement it:

Code:

DateTime Now = DateTime.Now.ToLocalTime();
byte[] buffer = new byte[36];
fixed (byte* Packet = buffer)
{
	*((ushort*)(Packet)) = (ushort)(36);
	*((ushort*)(Packet + 2)) = 1033;
	*((uint*)(Packet + 8)) = (uint)(Now.Year - 1900);
	*((uint*)(Packet + 12)) = (uint)(Now.Month - 1);
	*((uint*)(Packet + 16)) = (uint)Now.DayOfYear;
	*((uint*)(Packet + 20)) = (uint)Now.Day;
	*((uint*)(Packet + 24)) = (uint)Now.Hour;
	*((uint*)(Packet + 28)) = (uint)Now.Minute;
	*((uint*)(Packet + 32)) = (uint)Now.Second;
}
return buffer;

Could be that the source incorrectly assumes the time packet exists on this patch.

As far as I know, the client 5017 doesn't support the time packet.
