There has been a lot of discussion of the question below:
Can I land in a different time zone before my take off time?
The question as worded is really unclear and yet has received quite a few answers. Some of the better ones stating assumptions before giving an answer.
The question is generally silly and easy to check and answer but the bigger problem with it as I see it we allow question to stand without clarification, which for the quality of information on the site should have been made. So this naturally begs the question in the title.
