Need Help on date subtraction

I have dates as follows in a file

Code:
20121029135649
20121029135721
20121030091540
20121030093420
20121030094340
20121030095427
20121030095856
20121030100104
20121030100251

All these dates are in sorted order. I need to find out the difference between the dates as follows

2nd row date - 1st row date
3rd row date - 2nd row date
4th row date - 3rd row date

For eg:

Code:
20121029135649  20121029135721     difference in minutes
20121029135721  20121030091540     difference in minutes
20121030091540  20121030093420     difference in minutes
20121030093420  20121030094340     difference in minutes

I have tried using date -d "" +%s, but didn't find a correct solution.
I am using HP-UX OS. Please give me a solution.

INGRES_FETCH_OBJECT(3)							 1						    INGRES_FETCH_OBJECT(3)

ingres_fetch_object - Fetch a row of result into an object

SYNOPSIS
object ingres_fetch_object (resource $result, [int $result_type]) DESCRIPTION
This function is similar to ingres_fetch_array(3), with one difference - an object is returned instead of an array. Indirectly, this means that you can access the data only by the field names and not by their offsets (numbers are illegal property names). With regard to speed, the function is identical to ingres_fetch_array(3), and almost as quick as ingres_fetch_row(3) (the difference is insignificant). Note Related Configurations See also the ingres.fetch_buffer_size and ingres.utf8 directives in Runtime Configuration. PARAMETERS
o $link - The query result identifier o $result_type - (Optional argument.) $result_type is a constant and can take the following values: INGRES_ASSOC, INGRES_NUM, and INGRES_BOTH. RETURN VALUES
Returns an object that corresponds to the fetched row, or FALSE if there are no more rows EXAMPLES
Example #1 Fetch a row into an object <?php $link = ingres_connect($database, $user, $password); $result = ingres_query($link, "select * from table"); while ($row = ingres_fetch_object($result)) { echo $row->user_id; echo $row->fullname; } ?> SEE ALSO
ingres_query(3), ingres_num_fields(3), ingres_field_name(3), ingres_fetch_array(3), ingres_fetch_assoc(3), ingres_fetch_row(3). PHP Documentation Group INGRES_FETCH_OBJECT(3)
