WikiAnswers questions do have dates. The exact time that a question was submitted (and any other action taken, such as an answer or edit) is listed on the question's "History of Changes" page. See the blue tab at left. We don't make a big deal out of the dates because we think questions are timeless. Although the person who originally asked a question wants an answer ASAP, WikiAnswers is about growing questions and answers into permanent resources that will help thousands of people in the future.
To look at questions you've asked or contributed to look on your left sidebar and under "Quick Links" hit the button called "My Contributions". You can then look there for questions you have asked.
The majority of unanswered questions on Answers.com is not due to the answer being unknown... it is primarily due to the ambiguity of the questions for example... Why can't you answer some of my questions? Related Questions: Does the person who asked this question have an answer to a question and does not know how to post the answer? Does this person who asked this question wish to know why their question was left unanswered? As such it is highly recommended that questions be as specific as the answers the person who asked this question is searching for. Also, if your questions are not answered, you might want to put them in a category so it would be easier for someone to answer your questions. You can also add the questions unanswered to your watchlist.
