title: How to AWS trigger lambda on a specific time or date for n number of tasks?
body: <p>I have a scenario when i will have set of tasks to be executed at specific timing.
  for example</p>
  <pre><code>task1: 28-06-2020 1:00 AM
  task2: 30-06-2020 2:00 AM
  task3: 01-07-2020 12:00 PM

  .
  n
  </code></pre>
  <p>i want to trigger my lambda(where me logic is defined), at these specified timing.
  Probably i would be storing my timings to execute in a database,
  can some tell me a way to execute lambda at a specified time.
  I know we have TTL mechanism in dynamo which can trigger lambda but it delays the execution by 48 hours.I want my lambda to execute at the precise timings</p>
