Suggestion: config.groovy support default.date.format=yyyy-MM-dd HH:mm:ss z or Support new Date(1239425656319)

[Hubert Chang]

Now grails is locale aware and will change the dateformat according to the
user's locale. It's good.

I suggest there is an option to support a default date format for the whole
application. Then I can change the locale setting with the client
javascript.

I noticed that grails-ui and the calendar plugins all do some hacks to the
dateformat.

1, Support default.date.format=yyyy-MM-dd HH:mm:ss z in config.groovy
If we have this option,grails-ui and calendar plugins will have easy
method to handle the datetime. For example, they can get the option from the
config, and set up a hidden input field to format the datetime string to the
hidden input value.

Or,
2, support new Date(1239425656319) like JSON parser. It will give more
convenience.
if grails can check the input value with a unix-timestamp and parse it
like JSON, new Date(1239425656319), when it found a value is not a correct
format date string, it will eval it as new Date(1239425656319)
automatically, it will give some convenience to the developers too.

Thanks.

I agree

This is already possible in Grails 1.1 using default.date.format in message
bundles.
See GRAILS-3839 and GRAILS-3840.

However it's nowhere documented I believe.
I've raised GRAILS-4427 to document this feature.


Cheers,

I noticed that jira. It is for <g:formatDate> tag only. I mean an application
wide configuration.

I prefer to the second option.

When the server side get the date input data, it will check if it is an
unix-timestamp like '123456789000'. and if it is not an valid
unix-timestatmp, and also not an valid date format, it will throw an
exception.

Now for calendar plugin, grails-grails-ui plugin, <g:datepicker>, jquery-ui
plugin all do hacks to the date input. It is clear that the grails server
side doesn't provide a good option. If the server side can translate the
unix-timestamp, then the calendar plugin, grails-grails-ui plugin,
<g:datepicker>, jquery-ui plugin can translate the date with javascript
easily.
