FRAC_SECOND was mistakenly implemented with
a wrong resolution. According to the ODBC
standard it should be nanoseconds, not
microseconds. Changing it to nanoseconds
in MySQL would mean making TIMESTAMPDIFF
and TIMESTAMPADD to return DECIMAL, since
the return value would be too big for BIGINT
Hence we just deprecate the incorrect
implementation without changing its
resolution.
