def deadlines(t):
    \'\'\'shows pretty time to deadlines\'\'\'
    fmt = \'%a %d %m %Y %I:%M %p %Z\' 

    dt = datetime.strptime( t , fmt )

    print \'dt \', re

    %m matches months represent as a two-digit decimal (in [01, 12]). Use %b for abbreviated month names, or %B for full month names instead:

    fmt = '%a %d %b %Y %I:%M %p %Z'
    

    A table showing the date format directives and their meanings can be found here.


    If you're having trouble parsing PDT using %Z:

    Per the time.strptime docs:

    Support for the %Z directive is based on the values contained in tzname and whether daylight is true. Because of this, it is platform-specific except for recognizing UTC and GMT which are always known (and are considered to be non-daylight savings timezones).

    So, if parsing the date string without PDT works:

    In [73]: datetime.strptime('Sun 11 May 2014 05:00 PM', '%a %d %b %Y %I:%M %p')
    Out[73]: datetime.datetime(2014, 5, 11, 17, 0)
    

    but

    datetime.strptime('Sun 11 May 2014 05:00 PM PDT', '%a %d %b %Y %I:%M %p %Z')
    

    raises a ValueError, then you may need strip off the timezone name (they are, in general, ambiguous anyway):

    In [10]: datestring = 'Sun 11 May 2014 05:00 PM PDT'
    
    In [11]: datestring, _ = datestring.rsplit(' ', 1)
    
    In [12]: datestring
    Out[12]: 'Sun 11 May 2014 05:00 PM'
    
    In [13]: datetime.strptime(datestring, '%a %d %b %Y %I:%M %p')
    Out[13]: datetime.datetime(2014, 5, 11, 17, 0)
    

    or use dateutil:

    In [1]: import dateutil.parser as parser
    
    In [2]: parser.parse('Sun 11 May 2014 05:00 PM PDT')
    Out[2]: datetime.datetime(2014, 5, 11, 17, 0)
