title: AWS Lambda Timezone
body: <p>I've been searching for a while and can't find a definitive answer on that or any oficial documentation from AWS.</p>
  
  <p>I have a Lambda function on which I need to get the current date according to my timezone, but I'm unsure on which premisses I may rely to do that, and as this is a critical app, I can't simply rely on a single test or empirical result.</p>
  
  <p>I would expect that lambda functions follow the timezone of the AWS region that they are hosted in OR a unique timezone for any GMT 0, but couldn't confirm it anywhere.</p>
  
  <p>Could anyone please clarify how this works and if possible also point to any official documentation about that? Also, any special concerns related to daylight saving time?</p>
  
  <p>My Lambda function is written on NodeJS and what I've been doing locally (on my machine) to retrieve the current date time is using <code>new Date()</code>.</p>
