> We could add a "session time zone" like SQL and use that when it isn't
specified. We can then default the session time zone to UTC
That would work for me. We could set this as a property in the configuration.
> We could make helper methods for creating time literals, like
`timestamp(iso8601: str, defaultZone: str = "+00:00") -> int` that make it
clear what is happening by having a defined default
I'm less in favor of this one because I think this is mostly around the
filter API;
Instead of:
```python
tbl.scan(
row_filter=GreaterThanOrEqual("tpep_pickup_datetime",
"2022-01-01T00:00:00+00:00")
).to_arrow()
```
Have the API As:
```python
tbl.scan(
row_filter="tpep_pickup_datetime >= '2022-01-01T00:00:00+00:00'"
).to_arrow()
```
Then it is easy to forget the `+00:00` and then a user would need to look up
the format which is not very user-friendly. A logical evolution is also:
```python
tbl.scan(
row_filter="tpep_pickup_datetime >= '2022-01-01'")
).to_arrow()
```
Where `tpep_pickup_datetime` is a datetime. Setting a timezone on a date
would also be a bit awkward.
