Last year I had the luxury of spending much time watching two hives with new queens, actually I knew they where coming and happen to see one come out on the landing board on the way to check progress.
The 1st day I saw them, it was at 1:15 in the afternoon and low to mid 60's, so for 4 days I was there at noon. Each day they came out between 1-1:45, spent a little time on the landing board, then slowly lumbered off remarkably close times to each other. Longest I had one gone was 40 minutes, but I'm not sure if she sat in the trees any of that time, neither hit the landing board proper and had to walk in. The fourth, day only one left for a short period.
I would say it will depend most on how far to a DCA they have to go, weather (wind) and what perils they face during that time. From what I have read ( a few DCA studies online), shouldn't be to awful long and certainly not all day( my opinion)
I'm with kaizen, I'd wait a few days and check again
