问题
I have read a few stackoverflow posts but still can't figure this out...
I want to crawl craigslist post posted within last 48 hours. Posted time is in the following format for craigslist:
2013-03-15, 7:43PM MDT
I have tried
string = "2013-03-15, 7:43PM MDT"
time.strptime(string, "%Y-%m-%d, %I:%M%p %Z")
But apparent the format doesnt match the string. What should be the format for this time string?
回答1:
The problem is the MDT. Python's %Z doesn't support that (at least it seems so to me). There are probably better solutions, but this one should work:
import time
import datetime
#use the UTC which Python understands
a="2013-03-15, 7:43PM MDT".replace("MDT","UTC")
fs="%Y-%m-%d, %I:%M%p %Z"
c=time.strptime(a, fs)
#converting from UTC to MDT (time difference)
dt = datetime.datetime.fromtimestamp(time.mktime(c)) - datetime.timedelta(hours=6)
print dt
