時(shí)間在線計(jì)算器是一種可以實(shí)時(shí)計(jì)算兩個(gè)日期之間時(shí)間差的工具。要使用24小時(shí)的時(shí)間在線計(jì)算器，您需要提供起始時(shí)間和結(jié)束時(shí)間。以下是如何使用Python的datetime模塊來計(jì)算這兩個(gè)時(shí)間之間的差異：

from datetime import datetime, timedelta

def calculate_time_difference(start_time, end_time):
    start = datetime.strptime(start_time, '%H:%M')
    end = datetime.strptime(end_time, '%H:%M')
    difference = end - start
    return difference.total_seconds()

start_time = '08:30'
end_time = '17:45'
difference = calculate_time_difference(start_time, end_time)
print(f"時(shí)間差為 {difference} 秒")

請(qǐng)將start_time和end_time替換為您想要計(jì)算的時(shí)間。
