After further testing, when looking at the data retained in LF after QF reads a date of an image I have found that the date will advance to the next year whenever it is set to the last week of the year. For example, December 26 2015 (Sun) will work normally but December 27th 2015 (Mon) will be changed to the same date in 2016. This happens to every year with the exception to the case if the year's last day falls on a Saturday, or in other words, the year end coincindes with the week's end. Examples where the bug does not happen is December of 2011, 2016 and 2022.

I this a known issue or does anyone know why it happens?
