计算两个datetime.time实例之间的时间增量

import datetime

def calculate_time_difference(time1, time2):
    # 创建两个datetime对象，日期部分设置为相同的日期
    date = datetime.date.today()
    datetime1 = datetime.datetime.combine(date, time1)
    datetime2 = datetime.datetime.combine(date, time2)
    
    # 计算时间差异
    time_difference = datetime2 - datetime1
    
    # 提取时间差异中的小时、分钟和秒
    hours = time_difference.seconds // 3600
    minutes = (time_difference.seconds % 3600) // 60
    seconds = time_difference.seconds % 60
    
    # 返回时间增量
    return hours, minutes, seconds

# 示例用法
time1 = datetime.time(9, 30, 0)
time2 = datetime.time(12, 45, 30)
hours, minutes, seconds = calculate_time_difference(time1, time2)
print(f"时间增量为：{hours}小时 {minutes}分钟 {seconds}秒")

时间增量为：3小时 15分钟 30秒
