 >>> min(date)
'Fri, 8 Aug 2014 20:48:44 -0700 (PDT)'
The result is wrong,the min date should be 'Tue, 5 Aug 2014 01:55:24 +000
0 (UTC)' ,how can i get it ?

The result is probably correct (I haven't checked) as you're comparing 
strings.  I'll leave you to read the docs to find out how to convert the 
strings to datetimes and compare them.  Start here 
https://docs.python.org/3/ as that way you'll get used to finding your 
way around them.
