    SELECT 
    tp.*
FROM 
    trip_parameters tp
GROUP BY 
    CONVERT(UNIX_TIMESTAMP (tp.creation_time)/(2*60), unsigned)
ORDER BY
    tp.creation_time asc

    Note that using UNIX_TIMESTAMP does not allow you to handle dates beyond year 2037. Using the following instead fixes the problem:

    CONVERT(TIMESTAMPDIFF(SECOND,'1970-01-01 00:00:00',tp.creation_time)/(2*60), unsigned)
