Minutes since midnight in Momentjs

Question

In pure JS, this would be how.

How can I find out the number of minutes since midnight for a given moment object (without extracting to Date

Answer 1

This is what I have at the moment:

    if (!moment.isMoment(mmt)) {
        return 0;
    }
    var hh = mmt.get('hour');
    var mm = mmt.get('minute');
    return hh*60 + mm;

I am not sure if it takes into account various edge cases; comment if this is the case, or provide an alternate answer.
