@theducks - Cut & paste won't to a conversion - there is no ISO Date format in Excel 2007, nor I suspect was there such a thing in Quattro, or the grandfather of all such things - Visicalc.
It is crazy that it's easier to pivot a table, or do an FFT in Excel than it is to deal with ISO dates - but that's the way it is I'm afraid.
If I use a general format eg 'yyyy-mm-dd' against the string 2014-12-31T23:15:49+00:00 it wont be reformatted, if I substr the 1st 10 chars I get 2014-12-31 as a date (value rather than a string) - but the value I entered into calibre was 2015-01-01!
I still don't understand why pubdate and #mydate are held inconsistently when I enter the same value.
I tried defining all the dates as 'iso' to see if it would the overcome the inconsistency . But when I do that I can't even enter a full date; month and year is all I can get, see attachment. And the peculiar value in My Published, that was what I got when I clicked Set "My Published' to today - I'm guessing this is a cutie five glitch.
I'll retain the template derived columns, they do work and I can use Excel's formatting features to get dates on which I can do arithmetic.
