Declare two variables for all players like these:

Код:

new hellotime[MAX_PLAYERS];
new timerr[MAX_PLAYERS];

Create a prototype for the timer:

Код:

forward HelloPlayer(playerid);

When a player types "/hello":

Код:

timerr = SetTimerEx("HelloPlayer", 1000, true, "i", playerid);
hellotime[playerid] = 0;

And let's continue with our callback:

Код:

HelloPlayer(playerid)
{
hellotime[playerid]++;
if(hellotime[playerid] == 60) KillTimer(timerr[playerid]);
return 1;
}

-----------------------------------------------------------------------------------------------------------------------

Now we have to save the time if the player disconnect.

Код:

public OnPlayerDisconnect(playerid, reason)
{
new timeFile[128], name[24];
GetPlayerName(playerid, 24);
format(timeFile, 128, "time_%s", name);
if(!fexist(timeFile)) dini_Create(timeFile);
KillTimer(timerr[playerid]);
dini_IntSet(timeFile, "Time", hellotime[playerid]);
return 1;
}

You ought to load the 'hellotime' when the player connect.

Код:

public OnPlayerConnect(playerid)
{
new timeFile[128], name[24];
GetPlayerName(playerid, 24);
format(timeFile, 128, "time_%s", name);
if(fexist(timeFile))
{
hellotime[playerid] = dini_Int(timeFile, "Time");
timerr[playerid] = SetTimerEx("HelloPlayer", 1000, true, "i", playerid);
}
return 1;
}

I hope I helped you.
