Question

如何确保将 datetime.date.today() 转换为 UTC 时间？

到目前为止，这是我的代码:

#today : 2014-12-21
today = datetime.date.today()

#1900-01-01 16:00:00+00:00
timeformat = datetime.datetime.strptime('16:00', '%H:%M').replace(tzinfo=pytz.utc)

#combine today and timeformat  2014-12-21 16:00:00
now = datetime.datetime.combine(u, timeformat.time())
str_now =  now.strftime("%Y-%m-%d %H:%M:%S")

Answer 1

使用utcnow:

today = datetime.datetime.utcnow().date()
