Sorry to bother you again.
I tried upgrading to latest build 44 and %changeindaydec% is still 5-7 minutes off.
I have doubble checked the coordinates in the Sun/moon setup and they are correct.
%changeindaydec% says +05.11 - but the correct is +05.18. Right now the 5-7 minutes dosent mean much - but in late December and January/Febuary 5-7 minutes give a lot in difference.
