IncludeZeroSeconds option
If set to true or specified with no value (in which case, the default is true), specifies that "00" seconds values are unloaded into the external table. For example, a time value such as 12:34:00 or 12:34 is unloaded into the external table in the format 12:34:00.
If you do not specify the option, the default setting is false.
This option is not supported for the fixed-length format and is only for unloading.
