Subject [jira] Commented: (JSPWIKI-196) Date and time format accoding to ISO 8601
Date Sat, 23 Feb 2008 04:43:19 GMT

    [ https://issues.apache.org/jira/browse/JSPWIKI-196?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12571700#action_12571700

Andrew Jaquith commented on JSPWIKI-196:
----------------------------------------

Ok, that's fair comment. I'm not as knowledgeable as you are about how and when particular
JSPs do things like Comment.jsp does.

I may have erred in suggesting something a little to specific for all situations. However,
it seems that we both agree on the core issue: how to *write* dates to some destination (into
page markup, or as page metadata), and how to *display* dates ("render internal dates"). If
you modify your issue 3) above, you'll see that it makes sense: "...for cases where we *write*
the dates directly on the page content."

I suspect where you and the Goran might disagree is the correct internal format to use for
"write" operations. I don't have an opinion, although on balance I generally lean towards
configurable options, and away from hard-coded ones.

>          Components: Localization
>    Affects Versions: 2.6.1
>         Environment: Any
>            Reporter: Goran Karlic

> 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
22:38:10+0100")
> (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.
