Python-使用UTC时间戳检查它是否在另一个时区为DST

Question

我有一个UTC时间戳，我想检查当时是否是伦敦的夏令时。我将如何在Python中执行此操作？

Answer 1

您可以使用os.environ来设置您的时区。这是在两个不同时区检查DST的示例：

import time, os

os.environ['TZ'] = 'Europe/London'                                                                                                                                                      

timestamp = os.path.getmtime(filename) 
isdst = time.localtime(timestamp).tm_isdst > 0                                                                                                                                          


In [973]: timestamp

os.environ['TZ'] = 'USA/Colorado'                                                                                                                                                        

timestamp = os.path.getmtime(filename) 
isdst = time.localtime(timestamp).tm_isdst > 0

Out[968]: False
