Summary: I think, I have found this bug on time.mktime()

Initial Comment:
well, I think, I have found this bug on time.mktime() for dates less
than 1976-09-26

when I do stringtotime of 1976-09-25 

print "timeint %d" % time.mktime(__extract_date(m) + __extract_time(m) + (0, 0, 0)) 

extract date = 1976 9 25
extract time = 0 0 0
timeint 212454000
and 
timetostring(212454000) = 1976-09-24T23:00:00Z !? 

To be honest the date that kept me the action was the 1-1-1970 that
appears 31-12-1969. After timetostring(stringtotime(date)))

I made the test and time.mktime got a bug when date is less than
1976-09-26 
see:
for 1976-09-27T00:00:00Z time.mktime gives 212630400
for 1976-09-26T00:00:00Z time.mktime gives 212544000
for 1976-09-25T00:00:00Z time.mktime gives 212454000

212630400 - 212544000 = 86400 (seconds) , one day correct !
but
212544000 - 212454000 = 90000 (seconds), one day more 3600 (seconds),
more one hour ?!?
