Of course it won't... but it's the only accurate way (depending of the OOW really) to determine for how much time a ship was at sea... Why put a 8 hour minimum if they are going to ballpark it? They could have put one day for each day the ship was at sea or for each time, on a daily basis, that the ship was off the wall...
As for who was really on it, I guess if you want some accuracy you need to link it to posting messages, but even then, you'll miss some.
Hey, I finally figured out how to do 'quotes'!! (One extra beer this eve for me!)
Anyway, ship's sea days are indeed tracked (NavO) as is who is actually on the ship for that/those day/days(Cox'n). Where this info goes, I do not know but suspect where ever it is, that is where the info for the SSI comes from.
Everytime a ship sails from Halifax or Esquimalt, the Cox'n's Office creates a nominal role and the NOK box goes ashore. If you are repatted mid deployment, this gets recorded. If you stay ashore in St John's for 4 days between port visits because you were REALLY tired during a FISHPAT, this gets recorded. (trust me on this one!!!!)
Bottom line, the info is out there and has been collected since before World War II. It would seem that we now have a use for it!
Also, as NCdt is technically not a commissioned rank (don't start with the MS/MCpl thing again!), I am pretty sure there would be no curl.

By the way, anyone going to downtown Halifax tomorrow, today was an absolute mad house and for God's sake, if you have little kids, bring water. When I was out for my nooner walk, I bought 2 little boys a bottle of water each because mom and dad were whining and arguing about it being $3!
Best view? Get to know someone in PSU and get on a RHIB! - Seriously though, the walk from inside dkyd, through the south gate (Ark Royal and Wasp are at NB) at SCO all the way along the Boardwalk to beyond Pier 21. (Did I say bring water?) ATH is beside Sackville and TOR is with the Brazilian ship down by the NSPC building near Pier 21. There is also a new monument down there from the ACPOA. USN and RN vessels around Piers 21, 22, 23 as well....Enjoy!
