It was incorrect in the in game notification, so what will more people notice, something that notifies them to look at it or something that doesn't?
Assuming people who have been playing games more than a month, and who should be fully aware that human beings, even forum moderators, are imperfect? More people will, and should, notice the timer that is
visible any time they are in the game. There is no amount of pretense that makes it reasonable for people who have played for a long time, and are active on the forums, to come after-the-fact and whinge that the announcement was wrong and they didn't notice the timer any time during the ten days they were playing. Especially when there were several messages devoted to the fact that one of the in-game timers displayed the truncated days, while another displayed the days and hours. To repeat myself, none of that applies to new players, but it simply not reasonable for experienced players to rely on anything other than the timer that is visible nearly 100% of the time you are playing, or,
at the very least, at some point in the 10 days, to come to the forums and say "These don't agree, which is correct?".
