如何将EWS获取的datetime_received从UTC+0转换为GMT+2时区

需要将EWS接口获取的收件箱邮件datetime_received字段从UTC+0时区转换为GMT+2时区，原有测试代码如下：

credentials = Credentials(email, wachtwoord)
acc = Account(email, credentials=credentials, autodiscover=True)

for item in acc.inbox.all().order_by('-datetime_received')[:100]:
    print(item.datetime_received)
    # 输出：2021-13-09 11:08:31+00:00 
    # 预期输出：2021-13-09 13:08:31+02:00

解决方案 #

借助pytz库指定GMT+2对应的目标时区，调用astimezone()方法转换带时区信息的时间对象即可，完整实现代码如下：

from datetime import datetime
import pytz

credentials = Credentials(email, password)
acc = Account(email, credentials=credentials, autodiscover=True)
tz = pytz.timezone('Europe/Amsterdam')

for item in acc.inbox.all().order_by('-datetime_received')[:100]:
    dt = item.datetime_received.astimezone(tz)
    print(dt)
