如何将pandas Timedelta添加到特定业务和工作时间范围的时间戳

import pandas as pd

delta = pd.Timedelta(days=1, hours=2)

start_time = pd.Timestamp('2022-01-01 09:00:00')
end_time = pd.Timestamp('2022-01-01 17:00:00')

new_start_time = start_time + delta
new_end_time = end_time + delta

if new_start_time.time() < pd.Timestamp('09:00:00').time():
    new_start_time = new_start_time.replace(hour=9, minute=0, second=0)
if new_end_time.time() > pd.Timestamp('17:00:00').time():
    new_end_time = new_end_time.replace(hour=17, minute=0, second=0)
