问题描述
我正在尝试将utc日期字符串作为 YYYYMMDD
I am trying to get utc date string as "YYYYMMDD"
现在我要执行以下操作,
For now I do the following,
nowTime = time.gmtime();
nowDate = date(nowTime.tm_year, nowTime.tm_mon, nowTime.tm_mday)
print nowDate.strftime('%Y%m%d')
我曾经做过:
datetime.date.today().strftime()
但这给了我本地TZ的日期字符串
but this gives me date string in local TZ

推荐答案
from datetime import datetime, timezone
datetime.now(timezone.utc).strftime("%Y%m%d")
或者正如Davidism指出的那样,这也可以工作:
Or as Davidism pointed out, this would also work:
from datetime import datetime
datetime.utcnow().strftime("%Y%m%d")
我更喜欢第一种方法,因为它会让您养成使用时区感知日期时间的习惯-但正如JF Sebastian指出的那样-它需要Python 3.2+。第二种方法将同时在2.7和3.2分支中起作用。
I prefer the first approach, as it gets you in the habit of using timezone aware datetimes - but as J.F. Sebastian pointed out - it requires Python 3.2+. The second approach will work in both 2.7 and 3.2 branches.
