sorting multidimensional array by a second level value

[n_wattam]

I have an array $links like this:

[1] => Array
(
[href] => http://www.poetrymagazine.org/epstein_sept_prose.html
[description] => Thank You, No
[time] => 2004-09-17T17:30:32Z
)

[2] => Array
(
[href] => http://110am.com/projects/manuscript/
[description] => Manuscript
[time] => 2004-09-16T19:25:14Z
)

I'd like to sort the array based on one of the values in the field
href, description, or time. Is there a canonical way of doing this?
