-------------------------------------
Summary: [JS] Timestamp types are all the same
Key: ARROW-16543
URL: https://issues.apache.org/jira/browse/ARROW-16543
Project: Apache Arrow
Issue Type: Bug
Components: JavaScript
Reporter: Teodor Kostov
Current timestamp types are all the same. They have the same representation.
And also the same precision.
For example, {{TimestampSeconds}} and {{TimestampMilliseconds}} return the
values as {{1652118180000}}. Instead, I would expect the {{TimestampSeconds}}
to drop the 3 zeros when returning a value, e.g. {{1652118180}}. Also, the
representation underneath is still an {{int32}} array. Even though for
{{TimestampSeconds}} every second value is {{0}}, the array still has double
the amount of integers.
I also got an error when trying to read a {{Date}} as {{TimestampNanoseconds}}
- {{TypeError: can't convert 1652118180000 to BigInt}}.
