>>Why doesn't it show the dates of my last warnings?
Retroactive dates aren't possible. The time stamps are a new feature that are being stored in game. Future warnings will show your dates.
This is very important to consider here... there is a lot of "warnings" from a decade or more ago on a lot of characters.
You've been warned 5 times on the character xxx. You haven't been flagged as a high maintenance customer. You're not being monitored for vulgarity. You've last read the policy in full on Sun Apr 19 02:33:15 ET 2007.
For instance, this is a character I made almost 20 years ago... and I haven't been warned or in trouble in a very long long time...
