TV Show release date adds one day

Hi there,

I'm going through the imported TV shows in my library on iTunes 12.1.2.27 for Mac and adding all of the information for each episode, under Get Info.

An odd thing is happening regarding the "release date" field. Usually, there aren't any issues, however sometimes when adding the release date, it will appear fine under the Get Info dialog, yet appear incorrectly next to the title of the episode.

One example of this happening is specifically in the middle months of 2012, such as July.

The release date: 07/07/2012 (UK Date format DD/MM/YYYY)

The date as it appears in the Get Info window: 07/07/2012

The date as it appears next to the episode name in the library view: 08/07/2012

The date back in the Get Info window again: 07/07/2012

This happens for all TV shows, between March 24th and October 27th 2012.

March 25th 2012 appears as 26/03/2012 (incorrect). March 24th appears as 24/03/2012 (correct).

October 27th 2012 appears as 28/10/2012 (incorrect). October 28th 2012 appears as 28/10/2012 (correct).

Every single day in-between adds one day to the release date for the library view.

Anybody have any idea why this might be happening, or why the odd start and end dates for this bug? Why does it start on the 25th of March and not the start of April? Why end on the 27th of October and not the 31st?

Any help would be great, thanks!
