title: how can we convert timezone in azure data factory to specified timezones
body: <p>I want to write expression in a &quot;Set Variable&quot; activity and convert utcnow() to &quot;IST&quot; (Indian Standard Time&quot;</p>
  <p>I wrote the expression as : <strong>@convertTimeZone(utcnow(),'UTC','Indian Standard Time')</strong></p>
  <p>and I get the below error while I debug the pipeline:</p>
  <p><strong>In the function 'convertTimeZone', the value provided for the time zone id 'Indian Standard Time' was not valid. '.</strong></p>
  <p>I tried:</p>
  <p><strong>@convertTimeZone(utcnow(),'UTC','Pacific Standard Time')</strong></p>
  <p>and</p>
  <p><strong>@convertTimeZone(utcnow(),'UTC','Eastern Standard Time')</strong>
  and the debug runs just fine for both of these</p>
  <p>how to make it work for the cases where it doesn't ?</p>
