问题
I am trying to get utc date string as "YYYYMMDD"
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')
I used to do:
datetime.date.today().strftime()
but this gives me date string in local TZ
How can I get an UTC date string?
回答1:
from datetime import datetime, timezone
datetime.now(timezone.utc).strftime("%Y%m%d")
Or as Davidism pointed out, this would also work:
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.
