[python] Epoch 시간을 날짜 / 시간으로 변환

나는 나머지에서 응답을 받고있는 것은 Epoch 시간 형식입니다.

start_time = 1234566
end_time = 1234578

그 에포크 초를 MySQL 형식 시간으로 변환하여 MySQL 데이터베이스에 차이점을 저장할 수 있습니다.

나는 시도했다 :

>>> import time
>>> time.gmtime(123456)
time.struct_time(tm_year=1970, tm_mon=1, tm_mday=2, tm_hour=10, tm_min=17, tm_sec=36, tm_wday=4, tm_yday=2, tm_isdst=0)

위의 결과는 내가 기대 한 것이 아닙니다. 나는 그것을 좋아한다

2012-09-12 21:00:00

어떻게하면 좋을까요?

또한, 이유는 무엇입니까 TypeError: a float is required위해

>>> getbbb_class.end_time = 1347516459425
>>> mend = time.gmtime(getbbb_class.end_time).tm_hour
Traceback (most recent call last):
  ...
TypeError: a float is required

time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(1347517370))

>>> import datetime
>>> datetime.datetime.fromtimestamp(1347517370).strftime('%c')
  '2012-09-13 02:22:50'

>>> import datetime
>>> datetime.datetime.fromtimestamp(1347517370).strftime('%Y-%m-%d %H:%M:%S')
'2012-09-13 14:22:50' # Local time

>>> datetime.datetime.utcfromtimestamp(1347517370).strftime('%Y-%m-%d %H:%M:%S')
  '2012-09-13 06:22:50'

In [1]: time.time()
Out[1]: 1347517739.44904

In [2]: time.strftime("%Y-%m-%d %H:%M:%S", time.gmtime(time.time()))
Out[2]: '2012-09-13 06:31:43'

mend = time.gmtime(float(getbbb_class.end_time)).tm_hour

>>> import time
>>> time.strftime("%Y-%m-%d %H:%M:%S", time.gmtime(1347517119))
'2012-09-12 23:18:39'

INSERT INTO tblname VALUES (FROM_UNIXTIME(1347517119))

#This adds 10 seconds from now.
from datetime import datetime
import commands

date_string_command="date +%s"
utc = commands.getoutput(date_string_command)
a_date=datetime.fromtimestamp(float(int(utc))).strftime('%Y-%m-%d %H:%M:%S')
print('a_date:'+a_date)
utc = int(utc)+10
b_date=datetime.fromtimestamp(float(utc)).strftime('%Y-%m-%d %H:%M:%S')
print('b_date:'+b_date)

The ctime(), gmtime() and localtime() functions all take an argument of data type time_t which represents calendar  time.   When  inter-
       preted  as  an absolute time value, it represents the number of seconds elapsed since 00:00:00 on January 1, 1970, Coordinated Universal
       Time (UTC).

>>> time.time()
1347517171.6514659
>>> time.gmtime(time.time())
(2012, 9, 13, 6, 19, 34, 3, 257, 0)
