Question

我有一个获取时间的代码，并在GUI中显示和更新它。

我正在尝试更改代码，以使时间从零开始而不是从计算机获取时间。我试图从计算机上减去从计算机上花费的时间，以使时钟从零开始并递增计数，但这没有用。我正在尝试使其显示运行时间而不是实际时间。

import sys
from tkinter import *
import time
statusbar = Frame(root)
statusbar.pack(side="bottom", fill="x", expand=False)

time1 = ''
clock = Label(root, font=('times', 20, 'bold'), bg='green')

def tick():
    global time1
    # get the current local time from the PC
    time2 = time.strftime('%H:%M:%S')
    # if time string has changed, update it
    if time2 != time1:
        time1 = time2
        clock.config(text=time2)
        # calls itself every 200 milliseconds
        # to update the time display as needed
        # could use >200 ms, but display gets jerky
    clock.after(200, tick)

tick()

status = Label(root, text="Time:", bd=1, relief=SUNKEN, anchor=W)
status.pack(in_=statusbar, side=LEFT, fill=BOTH, expand=True)
clock.pack(in_=statusbar, side=RIGHT, fill=Y, expand=False)


root.mainloop()
