Subject: [PATCH] (bug 5727) Time magic words should use $wgLocaltimezone
 instead of UTC: 1. Not using anymore the functions wfTimestamp (for
 {{CURRENTTIME}}) and wfTimestampNow (for {{CURRENTTIMESTAMP}}) for the time
 magic words, because they output a UTC date; instead, using the built-in
 function "date" with the parameters "YmdHis". 2. Fix number 1 makes the time
 magic words OK when using the server default timezone (actually, all of them
 were OK except {{CURRENTIME}} and {{CURRENTTIMESTAMP}}), but the problem is
 still exist when setting $wgLocaltimezone, as it isn't noticed. Therefore,
 setting the timezone to "TZ" enviroment variable like in the signature,
 getting the various dates and times by "date" function, then setting the "TZ"
 to its previous value.
