title: I need many dates in ISO8601
body: <p>JAVASCRIPT</p>
  <p>Hello people how are you doing? I am new to Stackoverflow and new to coding. I finally figured out the code to give me date and time in this format</p>
  <p>2020-05-18T14:24-06:00</p>
  <p>With seconds and milliseconds too! The milliseconds took me like 30 minutes to figure out to make it 0.000 and 0.010 instead of just 0.0 or 0.01</p>
  <p>But I have a working ISO8601 string now.</p>
  <p>However whenever I change the timezone it changes it relative to my time not UTC.</p>
  <p>I want to have a drop down bar to add as many clocks as you need and I want to set them off of UTC how do you code for this?</p>
  <p>2020-05-18T14:24Z, 2020-05-18T14:24+01:00, 2020-05-18T14:24+02:00, 2020-05-18T14:24+03:00,
  2020-05-18T14:24+04:00</p>
  <p>And I can get the Zulu to ISO String but can I eliminate the milliseconds somehow?</p>
  <p>At the moment am just putting the code for the clock then manually adding on the &quot;-05:00&quot; I have 18 lines of code for one clock you guys and girls probably can help shorten it?</p>
