title: Swift get days since in PST issue
body: <p>I'm trying to get the days since in PST but I'm receiving the following <code>0001-01-01 07:52:58 +0000</code> when calling the method. The method is an extension on <code>Date</code> and the incoming date is the same format <code>2022-08-07 08:32:57 +0000</code>. Not sure where the error is.</p>
  <pre><code>func daysInPST() -&gt; Int {
          var components = DateComponents()
          components.timeZone = TimeZone(abbreviation: &quot;PST&quot;)
          let currentDateInPST = Calendar.current.date(from: components)
          let days = Calendar.current.dateComponents([.day], from: self, to: currentDateInPST!)
          return days.day!
      }
  </code></pre>
