title: storing time in database for users in different time zones
body: <p>I have a question about storing time for users in different time zones.  My wording may get a little coiled up, but please bear with me.  If I just store the time a user accesses my web app in UTC into MySql, then is it okay for me to disregard different time zones?  </p>
  
  <p>For example, say there are two users living across the world.  One says for both to chat in the web app at 4:00 his time.  So then the other person has to access maybe at 1:00 her time so that both can successfully meet up.  If I call UTC_Time() in Mysql when each of them logs onto the web app in their respective time, will I get one universal 4:00 for both of them?  Thank you very much.</p>
