I wonder if someone can point me in the right direction for a separate 
TOC which needs to be in chronological order at the back of the book 
(i.e. not in page number order, although I need the page numbers to show 
up in the TOC. There is the normal TOC at the front of the book, 
according to chapter titles.

I have succeeded in defining a separate TOC to place at the back, but 
have not succeeded in the chronological order! Here is what I have done:

\definelist[chron][criterium=all,alternative=c]

At the back of the book:

\placelist[chron][criterium=all]

Then at an appropriate point after each \startchapter I have placed (as 
an example):

\writetolist[chron]{}{{\bf 29 April 2017,} Speech, Panama City}

This gives me my list, but in page number order. How do I get the date 
(e.g. 29 April 2017) to be the ordering factor in the list. I assume it 
will be something to do with criterium, but am clueless at the moment on 
how to indicate this.
