SPRY - sorting UK dates

Question

I have created a SPRY sortable table in Dreamweaver CS4.  Two  columns are formatted as UK dates dd/mm/yyyy. They are identified as  dates in the SPRY table.
When sorting these date columns SPRY is  reading them as US date format which means the sorting is, while not  quite random, pretty meaningless.  I have checked this by reformatting  and displaying the date as US date format mm/dd/yyyy and then SPRY sorts  them as expected. 
Would appreciate some help with how I retain  the UK date appearance and achieve a sort on that basis.  Is there a  localisation file somewhere in the SPRY framework that allows date  formats to be identified?
If not, can anyone advise how to resolve this?
Thanks in advance for any help.

Answer 1

The root of the issue is that using JavaScript to a string into a date easily lead to inconsistent, unexpected results.
The way I solved this in the past is to have two columns inside my Spry datasets. One stores the date in yyyy-mm-dd format (ISO 8901, the format typically used by databases), another one stores a nicely formatted date (whatever format the language dictated).
Then I always display the nicely formatted column, but I sort it only the yyyy-mm-dd one.
As a bonus, yyyy-mm-dd sorts okay just as a string, so I have no need to assign a different datatype to it.
