Oracle - PL/SQL - TO_TIMESTAMP_TZ Function

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

The optional format_mask specifies the format of char. If you omit format_mask, 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.

The syntax for the to_timestamp_tz function is:

to_timestamp_tz( string1 , [ format_mask ] [ 'nlsparam' ] )

string1 is the string that will be converted to a timestamp with time zone.

format_mask is optional. This is the format that will be used to convert string1 to a timestamp with time zone.

The following is a list of options for the format_mask parameter These parameters can be used in many combinations.
