how to change the time string into number?

[luofeiyu]

in the manual  https://docs.python.org/3.4/library/time.html

%z 	Time zone offset indicating a positive or negative time difference 
from UTC/GMT of the form +HHMM or -HHMM, where H represents decimal hour 
digits and M represents decimal minute digits [-23:59, +23:59]. 	
%Z 	Time zone name (no characters if no time zone exists).


t1='Sat, 09 Aug 2014  07:36:46  '
time.strptime(t1,"%a, %d %b %Y %H:%M:%S ")
time.struct_time(tm_year=2014, tm_mon=8, tm_mday=9, tm_hour=7, 
tm_min=36, tm_sec
=46, tm_wday=5, tm_yday=221, tm_isdst=-1)

 >>> t2='Sat, 09 Aug 2014  07:36:46  -0700'
 >>> time.strptime(t2,"%a, %d %b %Y %H:%M:%S %z")
time.struct_time(tm_year=2014, tm_mon=8, tm_mday=9, tm_hour=7, 
tm_min=36, tm_sec
=46, tm_wday=5, tm_yday=221, tm_isdst=-1)

t1 and t2 is different time ,the timezone in t2 is -0700 ,why we get the 
same result?

 >>> t3='Sat, 09 Aug 2014  07:36:46  +0400'
 >>> time.strptime(t3,"%a, %d %b %Y %H:%M:%S %z")
time.struct_time(tm_year=2014, tm_mon=8, tm_mday=9, tm_hour=7, 
tm_min=36, tm_sec
=46, tm_wday=5, tm_yday=221, tm_isdst=-1)


The Directive   %z  has no any effect here,what is the matter?
