iPhoto '09 batch tool knows when to pluralize

When using the batch edit tool (Photos > Batch Change…) in iPhoto ‘09, the time drop-down menu will pluralize when editing the date. Enter a “1″ and hit tab, and the menu will change to “minute” from the default “minutes.” Same goes for Seconds, Hours, and Days as well. I’m not sure if this happened before iLife ‘09, and I can’t think of another app in the suite with which to test this.
