Review comment:
nit: Unneeded else. This might be clearer if the `if` bailed out.

> BigQuery to Beam SQL timestamp has the wrong default: truncation makes the

> Key: BEAM-8456
> URL: https://issues.apache.org/jira/browse/BEAM-8456
> Project: Beam
> Issue Type: Improvement
> Components: dsl-sql

> Priority: Major
> Time Spent: 1h 10m
> Remaining Estimate: 0h
>
> Most of the time, a user reading a timestamp from BigQuery with
> higher-than-millisecond precision timestamps may not even realize that the
> data source created these high precision timestamps. They are probably
> timestamps on log entries generated by a system with higher precision.
> If they are using it with Beam SQL, which only supports millisecond
> precision, it makes sense to "just work" by default.
