title: Date time difference using Ansible
body: <p>How to calculate the difference in seconds between below two date variables using Ansible.</p>
  <p>date1: 06/01/2021 00:10:15.434
  date2: 06/01/2021 00:10:26.667</p>
  <p>Tried to_datetime gives does not match format '%Y-%m-%d %H:%M:%S' error.
  If the dates are in yyyy-mm-dd format the difference calculation works, but not getting with above date format.</p>
