Stan... ask three different sources, get three different answers. ;-)
From my east valley location I get the following:
Sky Tools 2 says 16:29
Megastar 5 says 16:17
Starry Night Pro 5 says 16:22

Subject: [AZ-Observing] Polaris Transit

My sky program gives a transit time of Polaris for today, March 2, of 
16h 27m Mountain Standard Time. To check if the sky program I have is 
computing this correctly, would someone be able to verify this with the 
program they have? I am using Guide, ver. 8. At one time the "The 
Astronomical Almanac" published Polaris transit times, but they dropped 
that and in its place is the transit time of the Sun. I have verified 
the Guide program is computing the transit time of the Sun correctly, 
assuming the Almanac time is correct. However, unless I by hand compute 
the Polaris times from the Sun times (it is easy to make a mistake doing 
this), I have no way of knowing if Guide is computing the correct value.
