Don’t Be Late

I’ll be the first to say that UX is hard, but honestly now, do I really need to specify a dinner reservation time-of-arrival down to the second?

If I had to speculate, the implementor probably just copied an existing time input widget without consideration of the use case. Situations like this are a reminder of a downside of code reuse; yes it might say some development time, but is it best for the customer?
