@PublicEvolving public final class TimeType extends LogicalType
hour:minute:second[.fractional]
with up to nanosecond precision and values ranging from 00:00:00.000000000 to 23:59:59.999999999. Compared to the SQL standard, leap seconds (23:59:60 and 23:59:61) are not
supported as the semantics are closer to LocalTime. A time WITH time zone is
not provided.
The serialized string representation is TIME(p) where p is the number of
digits of fractional seconds (=precision). p must have a value between 0 and 9 (both
inclusive). If no precision is specified, p is equal to 0. TIME(p) WITHOUT TIME
ZONE is a synonym for this type.
A conversion from and to int describes the number of milliseconds of the day. A
conversion from and to long describes the number of nanoseconds of the day.

LogicalTypeA supported conversion directly maps an input class to a logical type without loss of precision or type widening.
For example, java.lang.Long or long can be used as input for BIGINT independent of the set nullability.

LogicalTypeA supported conversion directly maps a logical type to an output class without loss of precision or type widening.
For example, java.lang.Long or long can be used as output for BIGINT if the type is not nullable. If the type is nullable, only java.lang.Long can
represent this.
