title: Getting the user's "Last Seen" from a Telegram bot?
body: <p>When I chat with a telegram user, I can see for each user their "last seen" - when they last connected to Telegram (even if I haven't chatted with them for a while).</p>
  
  <p>Is there a way to query for this information via the bot <a href="https://core.telegram.org/bots/api" rel="noreferrer">API</a>? I haven't found a way to access it.</p>
