Bug when sorting games by created

Sorting games by the “Created” column incorrectly places games created yesterday after games created today, presumably because only the time of day is compared, and not the full datetime.

The issue names no file or test. Locate the game-list sorting entry point, reproduce the Created-column ordering with games from different dates, and inspect how their date values are compared. Done means sorting uses the full creation datetime so yesterday's games do not follow today's games solely because of their time of day.
