wish of those help In your func countdownInGUI, you created your Label widget by Label(root, text=entryInt), so tkinter will try to convert what you passed to a string. What you should do is to set entryInt as a textvariable instead.
On the other hand, you don't really need to set a textvariable for your Entry widget - you can retrieve the content directly by calling Entry.get().

code :

import tkinter as tk

class Application(tk.Frame):
    def __init__(self,master=None,**kwargs):
        super().__init__(master,**kwargs)
        self.master = master
        self.timeLeftLabel = tk.Label(master, text='Time Left: ')
        self.timeLeftLabel.pack()
        self.entryInt = tk.StringVar()
        self.countdown = tk.Label(master, textvariable=self.entryInt)
        self.countdown.pack()
        self.t = tk.Entry(master)
        self.t.bind('<Return>', self.start_countdown)
        self.t.pack(pady=5)

    def start_countdown(self,event=None):
        if self.t.get().isdigit():
            self.time_left(int(self.t.get()))

    def time_left(self, t):
        self.entryInt.set(t)
        t-=1
        if t>=0:
            self.master.after(1000,self.time_left, t)
        else:
            self.entryInt.set("Boom!")

root = tk.Tk()

frame = Application(root)
frame.pack()

root.mainloop()

Using SwingWorker and Timer to display time on a label?

By : Gonen Sheleg

seems to work fine You can do this without a SwingWorker, because this is what the Swing Timer is made for.

code :

int timeDelay = 1000;
ActionListener time;
time = new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent evt) {
        timeLabel.setText(DateTimeUtil.getTime()); 
        /* timeLabel is a JLabel to display time,
           getTime() is samll static methos to return 
           formatted String of current time */
    }
};

new Timer(timeDelay, time).start();

Unable to get the timer label to display time

should help you out You have a time.setVisible(false); but no time.setVisible(true);. It seems that you are making the label which displays Time: as visible but the label which displays the actual time is never made visible.

Display current time from javascript count up timer

Does that help Like some commenters mentioned, you should use clearInterval to stop the timer. You pass it the value returned by setInterval in timer.
You're already storing the minutes and seconds, so just use those DOM elements:

code :

function clearTimer() {
    if (timer_handle) {
        clearInterval(timer_handle);
    }
    alert(document.getElementById("minutes").innerHTML + ':' + document.getElementById("seconds").innerHTML);
}

Display current time from timer

this one helps. Your onclick function event is not bind correctly. To reset timer just reset timeleft var in button click function to 0

code :

var timeleft = 1;
    var downloadTimer = setInterval(function(){
    timeleft++;
    document.getElementById("countdowntimer").textContent = timeleft;
    if(timeleft >= 100)
        clearInterval(downloadTimer);
    },1000);
    
    
    
    function timenow()
{
  document.getElementById("timetaken").textContent = timeleft;
  timeleft=0;
  document.getElementById("countdowntimer").textContent = timeleft;
}

<p> Time   <span id="countdowntimer">0 </span></p>
<p> Time  Taken  <span id="timetaken">0 </span></p>
<button onclick="timenow()">Click to viw time taken</button>
