## Bug Report ### Which version of ShardingSphere did you use? master @ 7568693e8ee ### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy? Proxy ### Expected behavior When ShardingSphere-Proxy decodes a MySQL binary-protocol `TIME` value carrying a fractional second, the resulting `Timestamp` should carry the full sub-second value (e.g. 230000 microseconds on the wire yields 230,000,000 nanoseconds). ### Actual behavior The 4-byte fractional field holds microseconds, but `read()` passes it straight to `Timestamp#setNanos`, which expects nanoseconds. The value is decoded 1000x too small, so 230000 microseconds becomes 230,000 nanoseconds and the fractional second is lost. ### Reason analyze (If you can) In `MySQLTimeBinaryProtocolValue.read()` (case 12) `result.setNanos(payload.readInt4())` omits the microseconds-to-nanoseconds conversion. The sibling `MySQLDateBinaryProtocolValue.read()` already does `readInt4() * 1000`, and the same class `writeNanos()` writes `nanos / 1000`, so the read path must reverse it with `* 1000`. ### Steps to reproduce the behavior, such as: SQL to execute, sharding rule configuration, when exception occur etc. Send a MySQL binary-protocol `TIME` value with a non-zero fractional second (length 12 packet) through the proxy; the decoded `Timestamp` nanos are 1000x smaller than sent. ### Example codes for reproduce this issue (such as a github link).
