    timer: Fix incorrect minutes reset
    
    When resetting the timer, the values for the spinbuttons are determined
    from the timer starting amount in seconds. In order to get the correct
    number of minutes from this value, we must first account for the number
    of hours present (mod 3600) before converting from seconds to minutes
    (truncated division by 60).
