Wait, What? Strange Calculations for Travelling to Japan

I am looking at my flight itinerary for my trip to Japan and the numbers are very strange.
Take a look and see what you think.

Flight #1
Departure: 21 June  8:40 am:   Boston
Arrival:     21 June 10:31 am: Toronto
Duration: 1:51
Distance: 444.28 miles

Flight #2
Departure: 21 June 1:40 pm: Toronto
Arrival:     22 June 3:35 pm:  Tokyo
Duration: 12:55
Distance: 6426.22 miles

Flight #3
Departure: 22 June 7:55 pm: Tokyo
Arrival:     22 June 8:55 pm: Komatsu
Duration: 1:00
Distance: 195.73 miles

How many hours did I spend on all 3 flights together?
How long was the whole trip from start to finish?  How do you know?
I leave at 8:40 am on Thursday and arrive at 8:55 pm on Friday.  How does that make sense?
How many miles will I fly on my way to Komatsu?

Now take a look at my flight itinerary on the way back.  This time I leave at 5:40 pm on July 1st and arrive in Toronto at 4:45 pm on the same day.  How can this be?  Am I a time traveler????

Flight #1
Departure: 01 July 5:40 pm: Tokyo
Arrival:     01 July 4:45 pm:  Toronto
Duration: 12:05
Distance: 6426.22 miles

Flight #2
Departure: 01 July 8:55pm: Toronto
Arrival:     01 July 10:27pm: Boston

How many hours did I spend on the 2 flights together?
How long was the whole trip from start to finish?  How do you know?
How many miles will I fly on my way from Tokyo to Boston?
What did you need to know about time around the world to understand my crazy itinerary?
