Mac epoch?

While installing the Mac OS X 10.9 (Mavericks) update, I noticed that the temporary file ( /Applications/Mac OS X Mavericks.appdownload created while the update “app” downloads has the creation date set to January 24th, 1984, the day of the initial Macintosh release. I think this file will be removed by the installer when the download completes and the update installs, so it was a good place to hide something most people probably wouldn’t notice.


I wonder if 1/24/84 2:00 AM could be the standard the Macintosh epoch? At the time this page was rendered, the current UNIX time was [insert_php]echo time();[/insert_php] seconds after January 1 1970, 00:00:00 UTC, which works out to [insert_php]date_default_timezone_set(‘America/Chicago’);echo date(“F j, Y, g:i a”);[/insert_php] United States central time.

For the curious, the PHP functions return and format the seconds since UNIX epoch is as follows:

echo time();
echo date(“F j, Y, g:i a”);
