Are PHP DateInterval comparable like DateTime?

Question

I discovered that a DateTime object in PHP can be compared to another as the \">\" and \"<\" operators are overloaded.

Is it the same with DateInterval?

If you're working with time intervals that are not longer than a month, it's easy to convert 2 intervals to seconds and compare. $dateInterval->format("%s") only returns the seconds component so I ended up doing this:

function intervalToSeconds($dateInterval) {
        $s = (
            ($dateInterval->format("%d")*24*60*60) + 
            ($dateInterval->format("%h")*60*60) + 
            ($dateInterval->format("%i")*60) + 
            $dateInterval->format("%s")
        );
        return $s;
    }
