我有以下代碼在過去 5 年中在紐約證券交易所創建一個作業日表：
import pandas as pd
import datetime, pytz
import pandas_market_calendars as mcal
today_date = datetime.datetime.now(tz=pytz.timezone('US/Eastern'))
print(today_date)
start_date = datetime.date(today_date.year - 5, today_date.month, today_date.day)
print(start_date)
nyse_calender = mcal.get_calendar('NYSE')
print(nyse_calender.tz.zone)
nyse_business_days = nyse_calender.schedule(start_date=start_date,
end_date=today_date)
nyse_business_days
這是輸出：
market_open market_close

我實際上希望看到美國東部時區的時間，但事實并非如此。
例如，第一行的market_open應該是 2017-01-18 09:30 :00 00:00 但它顯示的是 2017-01-18 14:30 :00 00:00。
我應該怎么做才能在美國/東部的兩列中獲取時區？它以 UTC 顯示時區，但這不是我需要的。
附錄：
我根據@IanKenney 的評論嘗試了以下方法：
nyse_business_days["market_open"] = nyse_business_days["market_open"].tz_localize(pytz.utc).tz_convert(pytz.timezone('US/Eastern'))
當我列印出來時，我得到的是：
market_open market_close

uj5u.com熱心網友回復：
您可以嘗試以下方法來轉換時區
nyse_business_days['market_open'] = [t.tz_convert(pytz.timezone('US/Eastern')) for t in nyse_business_days['market_open']]
