read(DataInput in)
Overrides parent implementation to read only milliseconds (as a long) from the input stream, ignoring any nanoseconds written by TimestampType.write(). |

successor(Object value)
Returns the successor for the given value. |
boolean |
supportsSuccessor()
Returns true if the successor(java.lang.Object) method is supported, false
otherwise. |

void |
write(Object value,
DataOutput out)
Overrides parent implementation to always write time (in milliseconds) as a long, writing a placeholder zero for the nanosecond field usually written by TimestampType.write(). |
