Calibre 2.70 - {pubdate} is 1 year off

DrChiper · 10-14-2016, 07:21 AM

When I export books to disk, I use a template with contains {pubdate} to make up the file name. This worked until today.
Today, after installing version 2.70, I found that the resulting date (year) is 1 year off. So a pub date of 1991 in the database becomes according {pubdate} 1990, 2015 becomes 2014, etc.

Update: strangely, it does not happen always.

There weren't any changes to templates in 2.70. Most likely, this has always been the case. If you have a date like 1-1-1991:0:00UTC the database, when you use it in a template it is converted to the local timezone, which may be either 2-1-1991 or 31-12-1990 depending on your timezone.

Yes, that makes sense.

I checked and all those ill behaving ones had the date 01-01-XXXX. Most of the times I do know the publishing year, but do not know the publishing month, so I enter Jan 1st as the date. When I make that Jan 2nd, every time the correct year is now used.

I agree, this behavior is apparently not new but must have lingered a long time and I did not noticed it

Thanks!
