閏年的程式處理
其實還不少程式處理到閏年時會出錯的。最近新聞出現好幾則：
「うるう年」認識せず 豊川など３市３町、システム障害で窓口停止
輸入日期後，系統會檢查前後一年時間範圍內的相關資訊，但是前一年後一年都沒有 2/29，所以就會出現錯誤。
うるう年でエラー NTT東西の動画配信STBに不具合
機上盒在 2/29 那天會開不了機，呼籲若機器可用的使用者，不要關機。
ソニー、ワンセグ「ウォークマン」に”うるう年”問題－2月29日にEPGが取得できない不具合
Sony 的 1seg Walkman 在 2/29 那天無法取得 EPG （電子節目表），時間會變成 **:**，當然也無法預約錄影。
ｔｏｔｏ：販売が一時停止 コンビニのシステム不具合で
由於 FamilyMart 販賣系統沒有考慮閏年，足球彩券販賣中斷。
公衆電話故障の原因はソフトウェアの不具合
NTT 東日本與 NTT 西日本於 1/31 上午九點左右發現有電話故障（三千台以上），原因是：在電話費回收以後或電話機開關時，電話機會執行自我診斷程式，並且設定下次執行時間，而程式沒考慮到閏年，於是就故障了。
Exchange Server 2007 Bitten By Leap Year Bug / Exchange Server 2007 and leap year day Feb 29 2008…
Exchange Server 2007 某些設定功能會無法正常使用。（Microsoft Exchange System Attendant 的問題）
Warning: strtotime() [function.strtotime]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'UTC' for 'UTC/0.0/no DST' instead in /home/ericyu/public_html/blog/wp-includes/functions.php on line 35
