To define or change your time zone or how Teradata Database formats numeric, date, time, and currency output, use the command-line utility Teradata Locale Definition (tdlocaledef).
Tdlocaledef converts a specification for data formatting (SDF) text file into a Teradata Database globally distributed object (GDO), an internal binary format file that stores configuration information. The GDO is made available simultaneously to all nodes of an MPP system. The utility can also convert the text file to a local, non-distributed, binary file, that can be converted back to text in order to ensure the formatting syntax is valid.
For more details on the SDF file, see “SDF File” in the description of the Teradata Locale Definition (tdlocaledef) utility in Utilities.
