[Bug] Inserting 'Jacket' ended up with wrong year

nqk · 05-07-2015, 06:03 AM

Dear @kovidgoyal,

I use only year as value for published date. When I tried to insert a jacket, the year value in the jacket was the year before. For example, 2012 became 2011.

It turned out the value in the Metadata is 1/1/2012 ==> jacket year was wrong. If I changed it to any date after 1/1, then the jacket year was correct.

It's a time zone thing. The date is stored as a timestamp. It looks like "1975-01-02 00:00:00+00:00". The offset indicates it is UTC. The timestamp is converted to local time when the jacket is created. So, depending on what time zone you are in, and what is in the time part of the timestamp, the timestamp could represent a day earlier and hence the previous month and year.

So what should I do? I'm at GMT+7, using Calibre Portable.

Set the date more specifically.
