who can tell me why I use gmtime and mktime in python, get wrong result?

Question

I use python's time module to convert time_struct and timestamp:

mktime(gmtime(1404144000))

result is :

1404115200.0

who can tell me why?

what result do you want ? mktime returns a floating point number, for compatibility with time(). — scx, Aug 06 '14 at 12:22

mktime() is the inverse of localtime(), not gmtime()

mktime() takes a time tuple whose value is in localtime. Hence, this will give you the correct answer:

mktime(localtime(1404144000))

If you wish to operate on a time tuple in UTC, then conversion can be done by specifying the timezone:

mktime(gmtime(1404144000))-timezone
