In general, Presto displays dates, times and numeric data using the formats defined by the browser’s locale for the current user. If no locale information is available from the browser, Presto use the default system locale which typically is EN_us.

Some built-in views in Presto, allow users to choose a date and time pattern for result data such as mm/yyyy, for the month and year, or EEE MMM dd, yyyy, for the day of the week, month name, day and year. This pattern determines the components of dates or times that display in that view, but the language, order and delimiters used in the display are determined by the user’s locale or the default locale.
