WordPress 月や曜日を英語表記に。

いやなんか月とか曜日の表示を英語にしたかったんだ。
でも設定画面でそのような操作ができないようだったので、直接デリケートゾーン（wp-includes/locale.php）を弄くった。
本当はja.poだかja.moをいんぐりもんぐりするべきなんだろうけどね。
こっちの方が手間が掛からない感じ。
だからきっと真似はしない方がいいと思う。

	function init() {
		// The Weekdays
		$this->weekday[0] = 'Sunday';
		$this->weekday[1] = 'Monday';
		$this->weekday[2] = 'Tuesday';
		$this->weekday[3] = 'Wednesday';
		$this->weekday[4] = 'Thursday';
		$this->weekday[5] = 'Friday';
		$this->weekday[6] = 'Saturday';

		// The first letter of each day.  The _%day%_initial suffix is a hack to make
		// sure the day initials are unique.
		$this->weekday_initial['Sunday']    = 'Sun';
		$this->weekday_initial['Monday']    = 'Mon';
		$this->weekday_initial['Tuesday']   = 'Tue';
		$this->weekday_initial['Wednesday'] = 'Wed';
		$this->weekday_initial['Thursday']  = 'Thu';
		$this->weekday_initial['Friday']    = 'Fri';
		$this->weekday_initial['Saturday']  = 'Sat';

		foreach ($this->weekday_initial as $weekday_ => $weekday_initial_) {
			$this->weekday_initial[$weekday_] = preg_replace('/_.+_initial$/', '', $weekday_initial_);
		}

		// Abbreviations for each day.
		$this->weekday_abbrev['Sunday']    = 'Sun';
		$this->weekday_abbrev['Monday']    = 'Mon';
		$this->weekday_abbrev['Tuesday']   = 'Tue';
		$this->weekday_abbrev['Wednesday'] = 'Wed';
		$this->weekday_abbrev['Thursday']  = 'Thu';
		$this->weekday_abbrev['Friday']    = 'Fri';
		$this->weekday_abbrev['Saturday']  = 'Sat';

		// The Months
		$this->month['01'] = 'January';
		$this->month['02'] = 'February';
		$this->month['03'] = 'March';
		$this->month['04'] = 'April';
		$this->month['05'] = 'May';
		$this->month['06'] = 'June';
		$this->month['07'] = 'July';
		$this->month['08'] = 'August';
		$this->month['09'] = 'September';
		$this->month['10'] = 'October';
		$this->month['11'] = 'November';
		$this->month['12'] = 'December';

		// Abbreviations for each month. Uses the same hack as above to get around the
		// 'May' duplication.
		$this->month_abbrev['January'] = 'Jan';
		$this->month_abbrev['February'] = 'Feb';
		$this->month_abbrev['March'] = 'Mar';
		$this->month_abbrev['April'] = 'Apr';
		$this->month_abbrev['May'] = 'May';
		$this->month_abbrev['June'] = 'Jun';
		$this->month_abbrev['July'] = 'Jul';
		$this->month_abbrev['August'] = 'Aug';
		$this->month_abbrev['September'] = 'Sep';
		$this->month_abbrev['October'] = 'Oct';
		$this->month_abbrev['November'] = 'Nov';
		$this->month_abbrev['December'] = 'Dec';

		foreach ($this->month_abbrev as $month_ => $month_abbrev_) {
			$this->month_abbrev[$month_] = preg_replace('/_.+_abbreviation$/', '', $month_abbrev_);
		}

と思ったら同じやり方が紹介されていたからこの方法でもいいんじゃないかと。
小粋空間: WordPress の月および曜日を英語表記にする

よく見たらコードがなんとなく違っているのは、WordPressのバージョンが違うからだと思います。
上にダラダラーと掲載しているのは現時点で最近版である2.7.1のものです。
自己責任でいんぐりもんぐりしてみよう。

4月7日追記
冒頭で触れた「.po」ファイルを書き換えて「.mo」に変換する方法が丁寧に紹介されています。
勿論こちらが正攻法。
迷わず行けよ！行けば分かるさ！！
