Different New Horizons Pluto Closest Flyby Countdown Timer Ending

With the help of my son, we were able to use 1 laptop and 2 mobile phones to get the zero shot clock time of closest flyby of New Horizons to Pluto! Congratulations to Alan Stern and the New Horizons Team! Below are the screen grabs from my laptop, Samsung Note 4 and S4 respectively.

Below is a photo of Pluto taken by New Horizons at 16 hours and 766,000 kilometres from the surface. Latest flyby images unfortunately will take four hours to reach Earth as it is 5 billion kilometres away.
