对工作时间进行一定的计算，返回带有时刻的两个日期

import datetime

def calculate_working_time(start_date, end_date):
    # 定义工作时间的起始和结束时刻
    work_start_time = datetime.time(9, 0, 0)  # 9点
    work_end_time = datetime.time(17, 0, 0)  # 17点

    # 将日期和时刻合并为datetime对象
    start_datetime = datetime.datetime.combine(start_date, work_start_time)
    end_datetime = datetime.datetime.combine(end_date, work_end_time)

    # 计算工作时间的时长
    working_time = end_datetime - start_datetime

    # 返回带有时刻的两个日期
    return start_datetime, end_datetime, working_time

# 示例调用
start_date = datetime.date(2022, 1, 1)
end_date = datetime.date(2022, 1, 2)
start_datetime, end_datetime, working_time = calculate_working_time(start_date, end_date)

print("起始日期和时刻:", start_datetime)
print("结束日期和时刻:", end_datetime)
print("工作时间时长:", working_time)
