String Pattern representing the format in which you want the date returned. For pattern-string notation, see the “Pattern String Symbols” section.

String Optional. Time zone in which you want the output date and time expressed. Specify a time zone code as shown in the “Time Zones” section, for example, EST for Eastern Standard Time.

If you do not specify timezone, the value of the server's "user timezone" property is used. If this property has not been set, GMT is used.

String Optional. Locale in which the date is to be expressed. For example, if locale is en (for English), the pattern EEE d MMM yyyy will produce Friday 23 August 2002, and the locale of fr (for French) will produce vendredi 23 août 2002.

String Current date in the format specified by pattern.
