Snippet Name: TO_TIMESTAMP_TZ

Description: Converts a string datatype to a TIMESTAMP WITH TIME ZONE datatype.

Note: This function does not convert character strings to TIMESTAMP WITH LOCAL TIME ZONE. To do this, use a CAST function.

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.
