It's not the system clock you need to change for Google auth, you have to go into the auth app and sync it with Google's servers.

I'll agree that guy seriously got lucky with just 593 tickets winning 0.69 btc is the perfect way to end the year and enjoy the new year.
Sounds very lucky but nothing is impossible! I just wonder what percentage that is, like 1% I guess
Much less.
You can find the number of tickets but it's notmally a few hundred million if I remember rightly...
