28:37 So thanks for the questions, Paul. So First Alert is it's in many ways, it's the perfect first sizable acquisition for us. We've been looking at it for a while. And the business it's consistent with what we've communicated in terms of our overall M&A strategy because we've talked about the fact that ADI in particular, has the opportunity to do some small and medium-sized roll-ups, including the one that we just announced this week in addition to the ones that were done last year. That part of the strategy continues to march forward, and I'd expect that you'll continue to see those transactions. In aggregate they're not material, but overall, they're, they're additive. And the ones that we did last year, are now 100%, fully integrated, and they're performing above the level that we expected them to in terms of in terms of synergy and, and their own growth and margins. 29:34 Firstly, it falls into a different bucket, and we've tried to communicate this. And the bucket really is what we'll call the kind of regular way products and solutions, product line expansion type acquisitions. We always thought those would be more sizable. From a size standpoint, I think First Alert is a good example of the -- I hate to say, appropriate size, but it's not too big. It's not overwhelming, but it's of scale. And most importantly, it's probably the best hardware product fit in the market available for us. I mean we really believe that First Alert is we think we're the perfect owner for that business. In fact, going back 30 years, First Alert and our Security business, we're together in the same entity even before that entity was owned by Honeywell. So we're kind of bringing them back together. 30:30 And the opportunity here is this is a good business that we bought. Newell disposed of it because it didn't fit their portfolio. They're not in electronics manufacturing shop, but they took very good care of this business. They invested in R&D. They invested in advertising and promotion. They invested in some factory automation. So we're getting a very healthy business. The reason we can achieve the synergies that we can is because of the very close adjacency of the product lines, really the adjacency of the manufacturing and distribution facilities themselves. And from our perspective, given the valuation and the opportunity here, we see meaningfully more upside than we do risk from a deal like this in our hands.
