title: Do UNIX timestamps change across timezones?
body: <p>As the subject asks; do UNIX timestamps change in each timezone?</p>
  
  <p><strong>For example,</strong> if I sent a request to another email the other side of the world saying, <strong>"Send out an email when the time is 1397484936"</strong>, would the other server's timestamp be 12 hours behind my own?</p>
