--- Comment #11 from gnosy...@gmail.com ---
I just wanted to add a few points that may be of interest to someone.

(1) This error may become more common with wikidata and its time datatype. I
was looking at some errors in XOWA log files for ca.wikipedia.org and
discovered that Saint Nicholas (https://ca.wikipedia.org/wiki/Nicolau_de_Mira)
shows up as having died in 2003. See
https://ca.wikipedia.org/wiki/Categoria:Morts_el_2003 . He died in 343 A.D..

For those interested, here's the process:

* https://ca.wikipedia.org/wiki/Nicolau_de_Mira calls {{Sant}}
* {{Categoria per any de defunció}} is called
* {{#invoke:Wikidata|formatStatements|property=P570|formatting=year}} is called
* www.wikidata.org/wiki/q44269 defines P570 (year of death) as
+0343-12-06T00:00:00Z
* Note that this date adds an extra 0 at the beginning. Presumably this is a
bug related to dates with a year < 1000.
* This differs from other recent years of death 
: For example, Albert Einstein (www.wikidata.org/wiki/q937) has this as his
P570
+0001955-04-18T00:00:00Z
* Module:Wikidata calls lang:formatDate("Y", string.sub(d, 9, 18))
: This effectively becomes {{#time:Y|00343-12-0}} which generates 2003 (see
note (2) below for more info)
* The end result is Nicolau_de_Mira is listed as dying in year 2003:
https://ca.wikipedia.org/wiki/Categoria:Morts_el_2003

(2) Any 5 digit year appears to produce a 4 digit year using the following
method: "200" + 5th digit

=== 5 digit years ===
{{#time:Y-m-d|2-4-5}}  -> 2002
{{#time:Y-m-d|54321-4-5}}  -> 2001
{{#time:Y-m-d|12345-4-5}}  -> 2005
{{#time:Y-m-d|5-4-5}}  -> 2005

(3) 6+ digit years are basically random, depending on what the last 4 digits
are. I've gotten these type of results: current year; "19"+last_2_digits;
"200"+last_digit; random substrings in the string; invalid time

You can start with these examples, and then try reversing them, or inputting
random numbers

=== 6-14 digit years
{{#time:Y-m-d|12345-4-5}}   
{{#time:Y-m-d|123456-4-5}}  
{{#time:Y-m-d|1234567-4-5}} 
{{#time:Y-m-d|12345678-4-5}}
{{#time:Y-m-d|123456789-4-5}}   
{{#time:Y-m-d|1234567890-4-5}}  
{{#time:Y-m-d|12345678901-4-5}} 
{{#time:Y-m-d|123456789012-4-5}}
{{#time:Y-m-d|1234567890123-4-5}}
{{#time:Y-m-d|12345678901234-4-5}}

As for handling these in sprintfDate, I'm reluctant to make any changes until
PHP's DateTime also supports years >  because we could only provide partial
support without that.

Causing exceptions in production.

Example:


2014-02-01 17:38:26 mw1036 enwiki: [2ec80205]
/wiki/Special:FeedItem/featured/201402100/en   Exception from line 1131 of
/usr/local/apache/common-local/php-1.23wmf11/languages/Language.php:

/usr/local/apache/common-local/php-1.23wmf11/includes/specialpage/SpecialPage.php(374):

/usr/local/apache/common-local/php-1.23wmf11/includes/SpecialPageFactory.php(487):

#5 /usr/local/apache/common-local/php-1.23wmf11/includes/Wiki.php(599):

#8 /usr/local/apache/common-local/w/index.php(3): require('/usr/local/apac...')
#9 {main}

Language::date depends on Language::sprintfDate, which does not support TS_MW
values longer than 15 characters, but MWTimestamp::getTimestamp( TS_MW ) is
liable to generate 15-character values.

> $ts = wfTimestamp( TS_MW, 253402300800 )
> $wgContLang->date( $ts );
[b4a5f86b] [no req]   Exception from line 1131 of
/a/common/php-1.23wmf11/languages/Language.php: Language::sprintfDate: The
timestamp  should have 14 characters
Backtrace:
#0 /a/common/php-1.23wmf11/languages/Language.php(2045):
Language->sprintfDate(string, boolean)
#1 /a/common/php-1.23wmf11/maintenance/eval.php(71) : eval()'d code(1):

#2 /a/common/php-1.23wmf11/maintenance/eval.php(71): eval()
#3 /a/common/multiversion/MWScript.php(97): require_once(string)
#4 {main}

The immediate fix for FeaturedFeeds is to reject feed timestamps set so far in
the future as invalid.

The longer-term fix is to make the handling of >14 character timestamps
consistent across MWTimestamp and Language::sprintfDate, either by making
MWTimestamp decline to represent dates beyond 1-01-01 using TS_MW format,
or by making Language::sprintfDate handle TS_MW values longer than 14
characters.

Well now you're talking about different things...which sort of failures are you
talking about? Stuff involving math operations on dates probably is a
ParserFunction bug. Problems with date autolinking are MW core, but we're not
expanding that to non-English and might even remove it from English too making
it a non-bug. Stuff relating to tracking of revision timestamps and the like
won't be an issue for ~8000 more years.

If your math formulas involve future times, like astronomical calculation, you
MUST fix it right now.

WONTFIXing this, we will most likley not do this, or if we do it won't be for
ages since their isn't a pressing need for it.


But if you do desire feel free to work on it and send us patches for it.

Bumping back down, not a blocker... This isn't really a issue, This can be
