python - Converting Epoch time into the datetime

I am getting a response from the rest is an Epoch time format like

start_time = 1234566
end_time = 1234578

I want to convert that epoch seconds in MySQL format time so that I could store the differences in my MySQL database.

I tried:

>>> 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)

The above result is not what I am expecting. I want it be like

2012-09-12 21:00:00

Please suggest how can I achieve this?

Also,
Why I am getting TypeError: a float is required for

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

Answer

To convert your time value (float or int) to a formatted string, use:

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