String Pattern representing the format in which you want the time returned. For pattern-string notation, see the “Pattern String Symbols” section. If you do not specify pattern, dateTimeBuild returns null. If pattern contains a time zone and the timezone parameter is not set, the default time zone is used.

String Optional. The year expressed in yyyy or yy format (for example, 01 or 2001). If you do not specify year or you specify an invalid value, dateTimeBuild uses the current year.

String Optional. The month expressed as a number (for example, 1 for January, 2 for February). If you do not specify month or you specify an invalid value, dateTimeBuild uses the current month.

String Optional. The day of the month expressed as a number (for example, 1 for the first day of the month, 2 for the second day of the month). If you do not specify dayofmonth or you specify an invalid value, dateTimeBuild uses the current day.

String Optional. The hour expressed as a number based on a 24-hour clock. For example, specify 0 for midnight, 2 for 2:00 A.M., and 14 for 2:00 P.M. If you do not specify hour or you specify an invalid value, dateTimeBuild uses 0 as the hour value.

String Optional. Minutes expressed as a number. If you do not specify minute or you specify an invalid value, dateTimeBuild uses 0 as the minute value.

String Optional. Seconds expressed as a number. If you do not specify second or you specify an invalid value, dateTimeBuild uses 0 as the second value.

String Optional. Milliseconds expressed as a number. If you do not specify millis or you specify an invalid value, dateTimeBuild uses 0 as the millis value.

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.
