I like taking my time too. The best solutions come to me after days or weeks of chewing on the problem in the back of my head. Experienced interviewers know that this is how people solve problems. They know that time-boxing the problem is artificial, so they're not exactly evaluating you on how fast or slow you are within that time. The problems should be constructed in a way that lets them evaluate you based on your approach instead of on your solution. Sometimes it's just a bad interview question, or not the right question for you, the interviewee. Which is why interviewing takes practice, time, and patience, from both sides of the hiring market. It's far from perfect, but more "puzzle"-like questions aren't entirely useless as long as the interviewer really knows what they're doing and how to guide the interviewee.
