Subject: [PATCH] fix(games): put Infinity Nikki's America and Europe servers
 on their own clocks

Infinity Nikki resets at 04:00 on America UTC-7 and Europe UTC+2, not the
regional default, so the app rolled the day 2h early for American readers
and 1h late for European ones. Source: Game-Time-Master.

Re-labels the game-day of some already-logged ticks for those readers.
