### What happened? While trying to write to `TIMESTAMP` column in BQ a small value (for example `0001-01-01T00:00:00Z`), Storage Write API converter utility `TableRowToStorageApiProto` fails to convert from `String` to proto `INT64` with an error: ``` "org.apache.beam.sdk.io.gcp.bigquery.TableRowToStorageApiProto$SchemaDoesntMatchException: Problem converting field __root__.event_timestamp expected type: TIMESTAMP. Exception: java.lang.ArithmeticException: long overflow" ``` Reproduced on Apache Beam 2.41.0 SDK on GCP Dataflow. This is converter issue, as BQ perfectly supports such dates. --- After some investigation it seems problem was introduced with [[BEAM-13990] support date and timestamp fields](https://github.com/apache/beam/pull/17404/files#top), where [time conversion is done via](https://github.com/apache/beam/blob/master/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/TableRowToStorageApiProto.java#L441-L457): ``` return ChronoUnit.MICROS.between(Instant.EPOCH, Instant.parse((String) value)); ``` Internally, this hits [this](https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/time/Instant.java#L1154) and [this](https://github.com/openjdk/jdk/blob/master/src/java.base/share/classes/java/time/Instant.java#L1175) with values being `-62135596800 * 1000_000_000L`, which results `ArithmeticException: long overflow`. ### Issue Priority Priority: 2 ### Issue Component Component: io-java-gcp -- This is an automated message from the Apache Git Service.
