title: AWS Cloudwatch event - how to trigger for different timezones?
body: <p>I've got a bunch of AWS Lambda functions that I want to trigger at certain times of day, but those times are in different timezones. For example, I might want events to trigger at:</p>
  
  <ul>
  <li>4:55pm Sydney time</li>
  <li>6:30pm Chicago time</li>
  <li>9pm Chicago time</li>
  </ul>
  
  <p>...and so on.</p>
  
  <p>Using Cloudwatch events, regardless of which AWS region I use, it seems that I can only specify events to trigger using UTC (i.e. London time). For today, that's fine; I can work out the time differences between London and Sydney, and London and Chicago, and so on - however, summer time comes into effect on different dates in different cities, and it'll cause my Lambdas to trigger at the wrong times when it does.</p>
  
  <p>Is there a way to trigger these Cloudwatch events using non-UTC time settings? Alternately, is there a mechanism other than Cloudwatch that I can use to trigger Lambda functions at specific times of day, AND specify those times in the timezone I want?</p>
  
  <p>Thanks in advance</p>
