Sounds like your boss has a bug in her panties about the schedule, but bosses do take a lot of crap about schedules, from their employees and from their own bosses. I was awful about my own schedule, I should say that as a disclaimer right up front. My feeling is that you should have "eaten" that extra hour, gone window shopping, gone for a walk, stayed late and cleaned your desk, anything - but not made it your boss's "problem". I think that's all she was saying. It was a one-off, not that big of a deal.

I would talk to your t about why you feel embarrassed about it. I know - boy do I know - about feeling discounted by my bosses. Nothing they could do could make me feel special or that they recognized me "enough". But that is really like sibling rivalry issues brought into work, or attachment issues.

I would downplay it as much as possible at work, and let your t know it is a bit of an issue. My ts never believed me when I said it was a problem, but it would become a problem after a while, right? But I was so desperate for help, what could I do?
