Here's an actual example of using the PrintHintText for a countdown.

int Time = 10;

public Action Timer_CountDown(Handle timer, any client)
{
    if (!IsClientInGame(client) || !IsPlayerAlive(client))
        return Plugin_Stop;

    PrintHintText(client, "Warning!\nSomething will happen in: %i seconds", Time);
    Time--;

    if (Time <= 1)
    {
        return Plugin_Stop;
    }
    return Plugin_Continue;
}
