[issue23517] datetime.utcfromtimestamp parses timestamps incorrectly

[Tommaso Barbugli]

New submission from Tommaso Barbugli:

Hi,

I am porting a library from python 2.7 to 3.4 and I noticed that the behaviour of datetime.utcfromtimestamp is not consistent between the two versions.

For example on python 2.7.5
datetime.utcfromtimestamp(1424817268.274)
returns a datetime with 274000 microseconds

the same code in python 3.4 returns a datetime with 273999 microseconds.
