Hi,
We've got a chart which shows the development of Opportunities based on a snapshot taken every week (and recorded in a custom entity). These are organised by week number based on the date the snapshot was taken - a custom field rather than "created on" as this gives us a little flexibility to correct mistakes.
I've noticed that since the beginning of 2016 the week numbers have gone a bit weird, though. I've created some fake records with future snapshot dates and the following is happening:
27th December >> 31st December = week 53 2015 (correct)
1st & 2nd January = week 01 2016 (should still be week 53 2015)
3rd January >> 9th January = week 02 2015 (should be week 01 2016)
etc. (all future dates are 1 week ahead)
Does anyone know what could be causing this? Is it a bug?
Thanks!
Stephen
