Unix billennium

A second has an exactly defined length; a leap second does not change the length of second, so the distinction does not apply.).

1000000000 seconds parties were held around the world on the day in question.

The Unix billennium is the point in time represented by a Unix time value of 109: 01:46:40 UTC on September 9, 2001. Some programs which stored timestamps using a text representation encountered sorting errors, as in a text sort times after the turnover, starting with a "1" digit, erroneously sorted before earlier times starting with a "9" digit. Affected programs included the popular usenet reader KNode and e-mail client KMail, part of the KDE desktop environment. Such bugs were generally cosmetic in nature and quickly fixed once problems became apparent.

The problem also affected many 'Filtrix' document-format filters provided with Linux versions of WordPerfect; a patch was created by the user community to solve this problem, since Corel no longer sold or supported that version of the program.

The name is a portmanteau of "billion" and "millennium".
