Description

TO_TIMESTAMP_TZ converts char of CHAR, VARCHAR2, NCHAR, or NVARCHAR2 datatype to a value of TIMESTAMP WITH TIME ZONE datatype.

The optional fmt specifies the format of char. If you omit fmt, then char must be in the default format of the TIMESTAMP WITH TIME ZONE datatype. The optional 'nlsparam' has the same purpose in this function as in the TO_CHAR function for date conversion.

Syntax:

TO_TIMESTAMP_TZ(char [, fmt [, 'nlsparam' ] ])

char	The CHAR, VARCHAR2, NCHAR, or NVARCHAR2 datatype value to be converted.
fmt (Optional)	Specifies the format of char. Default: Format of the TIMESTAMP WITH TIME ZONE.
nlsparam (Optional)	Specifies the language in which month and day names and abbreviations are returned. This argument can have this form : 'NLS_DATE_LANGUAGE = language'.
