title: Express time as CST in javascript - date-fns
body: <p>I am using date-fns to format dates</p>
  <p>If I pass a date that ends in Z, it knows that it is UTC, and I can <code>format(date, &quot;yyyy-MM-dd&quot;)</code> and it will be in local computer time.</p>
  <p>If the date I want to express in local computer time is originally CST, is there something to add at the end instead of the Z, that will be understood by the format function as a CST date?</p>
  <p>Sorry if this is a bad question</p>
  <p>Edit: is there a way to do <code>zonedTimeToUtc(myDate, 'UTC-6')</code> in date-fns? (instead of using a time zone <em>name</em>)</p>
