title: Change Visual Studio "Current regional settings" value
body: <p>I'm designing some SSRS reports in Visual Studio and every datetime field is displaying as MM/dd/yyy instead of my preference of dd/MM/yyyy</p>
  
  <p>My Windows regional settings are English(Ireland) but if I look at any datetmie placeholder propery window it shows "Current regional settings: English (United States)".
  I don't know where it's picking this up from (pretty certain it's not the SQL login defined in the dataset either) or how to change it. Any ideas?</p>
  
  <p>(I could forcibly change the output of every datetime field to my preferred format would would like to not have to do this every time and instead just get the environment into the right regional setting)</p>
  
  <p><i>Update: Forgot to add, I can see a Language tag in the RDL which is set to "en-US" and whenever I try to change that to anything else and save it automatically changes back to "en-US"</I></p>
