This is using sscanf2.5. This tool is especially useful for commands such as this.

pawn Код:

if(!strcmp(cmdtext,"/reload",true))
{
    if(!IsPlayerAdmin(playerid)) // If they are not Admin then it sends the message
    {
        return SendClientMessage(playerid,-1,"You are not authorised to use this command.");
    }
    new gmxdelay; // A new variable that the player will type after typing "/reload"
    // This is the line that checks if they didn't type the command correctly.
    if(sscanf(params,"d",gmxdelay))
    {
        // So if they didn't type it correctly then tell them how to use it.
        return SendClientMessage(playerid,-1,"Syntax: /reload <minutes>");
    }
    if(gmxdelay == 0) // If they typed 0
    {
        return SendClientMessage(playerid,-1,"It must be at least one minute.");
    }
    else
    {
        // The "gmxdelay*1000*60" is what converts it to minutes.
        // gmxdelay is multiplied by 1000, which is one second
        // that product is then multiplied by 60 to equal a minute
        SetTimer("gmxtimer",gmxdelay*1000*60,false);
        new
            string[128]; // A new optional string to format
        format(string,sizeof(string),"The server will restart in %d minute.",gmxdelay);
        SendClientMessageToAll(-1,string);
    }
    return 1;
}
forward gmxtimer();
public gmxtimer() // So once the timer is up, then it....
{
    // sends the gmx command to RCON
    SendRconCommand("gmx");
}

Here is the same example with ZCMD.

CMD:reload(playerid,params[])
{
    if(!IsPlayerAdmin(playerid)) // If they are not Admin then it sends the message
    {
        return SendClientMessage(playerid,-1,"You are not authorised to use this command.");
    }
    new gmxdelay; // A new variable that the player will type after typing "/reload"
    // This is the line that checks if they didn't type the command correctly.
    if(sscanf(params,"d",gmxdelay))
    {
        // So if they didn't type it correctly then tell them how to use it.
        return SendClientMessage(playerid,-1,"Syntax: /reload <minutes>");
    }
    if(gmxdelay == 0) // If they typed 0
    {
        return SendClientMessage(playerid,-1,"It must be at least one minute.");
    }
    else
    {
        // The "gmxdelay*1000*60" is what converts it to minutes.
        // gmxdelay is multiplied by 1000, which is one second
        // that product is then multiplied by 60 to equal a minute
        SetTimer("gmxtimer",gmxdelay*1000*60,false);
        new
            string[128]; // A new optional string to format
        format(string,sizeof(string),"The server will restart in %d minute.",gmxdelay);
        SendClientMessageToAll(-1,string);
    }
    return 1;
}
forward gmxtimer();
public gmxtimer() // So once the timer is up, then it....
{
    // sends the gmx command to RCON
    SendRconCommand("gmx");
}

Hope I was of any help.
