Subject [jira] Created: (JSPWIKI-244) Rendering Date and Time from Plugins
Date Thu, 10 Apr 2008 11:04:06 GMT
Rendering Date and Time from Plugins

                 Key: JSPWIKI-244
                 URL: https://issues.apache.org/jira/browse/JSPWIKI-244
             Project: JSPWiki
          Issue Type: Improvement
          Components: Localization
    Affects Versions: 2.6.1
         Environment: Any
            Reporter: Goran Karlic
            Priority: Trivial

+This issue was changed to better reflect the initiated discussion+

Focus is on:

* How DateTimes are *stored* internally, for example as page content or metadata (comments
* How they are *rendered* to end-users in their browsers

The original issue name was:  _Date and time formats according to ISO 8601_. 

We have multiple occurences of hard-coded or context-unaware DateTime to String conversions
(page properties, JSPs, templates).

My proposal is to rely on an international standard instead of using an invented default.
The current international standard is ISO 8601 (s. Wikipedia). My further proposal is to show
time with the precision to the second, as the SI unit system defines the second as the basic
unit of time. Furthermore "GMT" is replaced by "UTC" and they might differ up to a second
(s. Wikipedia).

I think this will make unlocalized strings more transparent to the users and easier to decode
correctly (consider 02/03/08 - is it in the future or in the past - or might it even be the
current time?!).

Following this proposal java format strings allowed for above cases would be: 

(1) Simple date: "yyyy-MM-dd" ("The daily mail for 2008-02-20 was sent")
(2) Date and time
(2.1) Explicit time context: "yyyy-MM-dd hh:mm:ssZ" ("User gkarlic made this at 2008-02-20
(2.2) Implicit time context: "yyyy-MM-dd hh:mm:ss" ("This server lives on CET, here it is
2008-02-20 22:38:10")

Where (2.1) would be used for strings that might emerge from different time-zones.

If others agree with this proposal, I would gladly make the required changes.
