I am trying to get utc date string as "YYYYMMDD"

For now I do the following,
现在我做以下事情，
nowTime = time.gmtime();
nowDate = date(nowTime.tm_year, nowTime.tm_mon, nowTime.tm_mday)
print nowDate.strftime('%Y%m%d')
I used to do:

datetime.date.today().strftime()
but this gives me date string in local TZ

采纳答案by Matt Johnson-Pint
from datetime import datetime, timezone
datetime.now(timezone.utc).strftime("%Y%m%d")
Or as Davidism pointed out, this would also work:
或者正如大卫主义所指出的，这也行得通：
from datetime import datetime
datetime.utcnow().strftime("%Y%m%d")
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.
我更喜欢第一种方法，因为它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+。第二种方法适用于 2.7 和 3.2 分支。
