Question

I have a form that includes a date field. The user can click on the calendar icon and click on the date. When this happens the calendar pop up goes away and the date is now populated in the date field of the form. For example, the date displayes as 28 Aug 2008. How can I change it so the date displays as 2008/08/28? I tried changing the default date format in configure but it still comes out as 28 Aug 2008 in the form. Thanks for the help!

I think the date format is controlled by a JSCalendarContrib. Set this in twiki/lib/LocalSite.cfg setting:

$TWiki::cfg{JSCalendarContrib}{format} = '%Y-%m-%d';

to get sortable ISO dates such as 2026-02-16

Thank you Peter! That did the trick. I know people utilize TWiki for many different things but maybe this would be a better default date format that comes with the initial install. I prefer this format so sorting on dates is easily done. Thanks again!

I Peter's trick too: even better than changing the default format would be if the formfield date used the existing configure setting of {DefaultDateFormat}. Then we wouldn't need this tip.

That is what i proposed in UseIsoDates, which was implemented with a compromise, e.g. no change in the default format to ISO date. Please open a new enhancement request to lobby for that useful change.

I'm not sure that ISO should the default, because some (mostly Americans? ) object to it. The format should only have one configuration point though. That might make it possible to be a user preference too?

The enhancement request is covered by ConvergeDateTimeFormattingModels?
