如何计算鼠标移动的时间？

Question

我有这个描述鼠标移动的代码

import sys 
import math
import time
from datetime import datetime


from PyQt5.QtGui import *
from PyQt5.QtWidgets import *
from PyQt5.QtCore import *
from toolz.itertoolz import second

class Frame:
    def __init__(self, position, time):
        self.position = position
        self.time = time

    def speed(self, frame):
        d = distance(*self.position, *frame.position)
        time_delta = abs(frame.time - self.time)
        return d / time_delta
if __name__ == '__main__':
    app = QApplication(sys.argv)

    last_frame = get_current_frame()

我想要计算鼠标移动时的时间。 我怎么能设置一个定时器，每当鼠标移动一秒钟时，它会做+1秒？
