Feature Proposal: Use ISO Dates by Default

Motivation

Use ISO date (such as %SERVERTIME{$year-$mo-$day}%) by default in TWiki distribution for 2 reasons:

• avoid ambiguity across locales
• easily sort dates

Description and Documentation

1. Default date setting in configure

UseIsoDates has been implemented so that an administrator can set the the date format in configure by selecting from options $day $month $year, $year-$mo-$day, $year/$mo/$day, $year.$mo.$day.

The current default is $day $month $year. I suggest to change that to ISO format $year-$mo-$day in the next 4.3 patch release.

2. Default date setting in JSCalendarContrib

lib/TWiki/Contrib/JSCalendarContrib.pm currently defaults to '%e %B %Y'. I suggest to change that to ISO format '%Y-%m-%d'. In addition I suggest to add $TWiki::cfg{JSCalendarContrib}{format} = '%Y-%m-%d'; to TWiki.spec.

Examples

TWiki.org has been configured already for ISO dates. It can be seen in signatures and forms with date pickers.
