Array merge on similar key => value

I have three arrays I'm working with based on queries pulled from a database. All of them have one key => value pair in common, and I'm looking for the most elegant way to merge these arrays.

array_merge() of course won't work, and I'm curious if there's a better solution than iterating through and merging it 'by hand' so to speak within a loop.

For example, the arrays all follow this paradigm;

Code:

Array
(
    [0] => Array
        (
            [timestamp] => 2009-10-23
            [key_one] => value_one
        )

....

Array
(
    [0] => Array
        (
            [timestamp] => 2009-10-23
            [another_key] => another_value

        )

The desired result, is of course;

Code:

Array
(
    [0] => Array
        (
            [timestamp] => 2009-10-23
            [key_one] => value_one
            [another_key] => another_value
        )
