30:40 Sure, Selman. Yeah. In terms of pricing that we use in our kind of forecasting, but we typically are very conservative, and we'll look at kind of where pricing state -- where pricing is sitting right now. And so, I think that would be consistent with how we approach the guidance amount. So certainly nothing too crazy. No big assumptions on kind of hockey you stick price increases. I would tell you we are on the large horsepower stuff, in particular, we are seeing strong pricing, but really large stuff to utilization is way up. And so, I think as that happens. As we get through the year, I mean, again, we're early, but as we get through the year, we'll be able to -- I think as utilization moves, we'll be able to kind of, at that point evaluate this pricing need to move, but certainly in the guidance, we've taken a pretty conservative event. 31:50 On the inflationary stuff, it's interesting. We looked just as a titbit last year over the course of 2021 at our labor costs in particular, because there's been a lot of headline noise there about costs and whatnot. And our average labor on a dollar per hour basis went up over the course of the year, went up anywhere from 2% to 4%. And so, that's kind of in line with what we had seen historically in line with what we expect this continuing year. And again, we're not -- the vast majority of our employees are guys on the field, they're skilled, skilled folks who we're not talking minimum wage stuff. And so we expect that to -- we'll see some increase I think again, in field wages et cetera in line with kind of what we've seen in the past, but not expecting huge, huge moves. 32:39 And then the other things, parts lube oil, those kinds of things, parts and both of them, we've actually done a pretty good job. We've locked in some pricing before the end of the year. And so we have awarded some kind of early 2022 price increases that went out. And so we've tried to manage that as best we can. And then of course, the other way we work through that is through the CPI price escalators. And making sure that we're passing on the increased cost to customers. So it's a combination of sort of managing it actively in terms of locking in some prices, but also having the flexibility in our contracts to go through and push through those price increases.
