Last week, less than 7 days ago, the battle.net desktop app showed that I had 12 days of game time left. Two days ago, the battle.net desktop app showed that I had 4 days of game time left. This morning, the battle.net desktop app showed that I had 9 hours of game time left. After closing and reopening the battle.net desktop app, it now shows that I have 13 days of game time left. THIRTEEN DAYS. Why the inaccuracy?
I have not adjusted my computer’s clock or calendar at all in the past few months.
