Bug #: 30472
Summary: Apply rightpadding to truncated timestamps in #time
Product: MediaWiki extensions
Version: any
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: Unprioritized
Component: ParserFunctions
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
Related to bug 28655 and bug 13357, this apply to pure-numeric integer
date/time objects only, ie. "truncated timestamps", especially those of 4 or 6
digit length.
Regardless of PHP bug causing some misinterpretations, those issues can be
overridden applying
{{padright: {{padright: «truncated timestamp» | 8 | 01 }} | 14 | 0 }}
Thus converting all pure-numeric integer objects in complete 14 digit
timestamps.
Current outputs:
{{#time: Y | 1998 }} → 1998 (partially fixed since rev:86805)
{{#time: Y M d H:i:s | 1998 }} → 1998 Aug 19 00:00:00 (expected 1998 Jan 01)
{{#time: F Y | 200611 }} → August 2011 (expected November 2006)
{{#time: Y M d H:i:s | 200615 }} → 2011 Aug 19 20:06:15 (expected error)
{{#time: Y M d H:i:s | 199804 }} → Error (expected 1998 Apr 01 00:00:00)
Now using padrighted inputs:
{{padright: {{padright: 1998 | 8 | 01 }} | 14 | 0 }} → 19980101000000
{{padright: {{padright: 200615 | 8 | 01 }} | 14 | 0 }} → 20061501000000
{{padright: {{padright: 199804 | 8 | 01 }} | 14 | 0 }} → 19980401000000
{{padright: {{padright: 19980425340712 | 8 | 01 }} | 14 | 0 }} → 19980425340712
{{#time: Y M d H:i:s | 19980101000000 }} → 1998 Jan 01 00:00:00 (OK)
{{#time: Y M d H:i:s | 20061501000000 }} → Error (OK)
{{#time: Y M d H:i:s | 19980401000000 }} → 1998 Apr 01 00:00:00 (OK)
As right padding forces the system to make a date interpretation (instead of
time interpretation) of ambiguous 4 or 6 digit integer input data, we should
have a way to opt to do this pre padding, or not. This option may be achieved
by a new 'xd' flag ('d' related to date interpretation). It should be a toggled
flag like xN and it should work as follows:
{{#time: xdY | 2006 }} → 2006
{{#time: xdF Y | 200611 }} → November 2006
{{#time: xdY m d H:i:s | 200615 }} → Error
{{#time: xdY m d H:i:s | 199804 }} → 1998 04 01 00:00:00
{{#time: xdY m d H:i:s | 1998 }} → 1998 01 01 00:00:00
