outputBlock.Text &= String.Format("The universal time zone is {0}.", universalZone.DisplayName) & vbCrLf
outputBlock.Text &= String.Format("Its standard name is {0}.", universalZone.StandardName) & vbCrLf
outputBlock.Text &= String.Format("Its daylight savings name is {0}.", universalZone.DaylightName) & vbCrLf
