Description

When using an Instant type in a TableRow, and a TIMESTAMP field in the TableFieldSchema, one has to convert the Instant via

instant.getMillis() / 1000

to match the BigQuery TIMESTAMP that is "A positive or negative decimal number. A positive number specifies the number of seconds since the epoch".

In the Dataflow 1.9 SDK this conversion is done automatically.
