When you use the configuration parameter timestamp_ms_support,
consider specific conditions.
When timestamp_ms_support equals 0, Sybase TIME and
DATETIME datatype is accessible, but the millisecond portion of an
Oracle TIMESTAMP contains 000 (zeros).
When timestamp_ms_support equals 1, Sybase TIME and
DATETIME datatype is able to insert,
update, delete, or select the
millisecond portion of an Oracle TIMESTAMP.

The Adaptive Server version must be 12.5.1 ESD #2 or later to use the
timestamp_ms_support configuration option. This is due to changes that
were made in Adaptive Server/CIS 12.5.1.

The timestamp_format configuration setting must include the milliseconds
(...SS.FF) if the millisecond portion of the time is desired, and the
timestamp_ms_support parameter must be equal to 1.
