@ashb I experimented with using `datetimeoffset` rather than `datetime2` but
unfortunately it doesn't seem to help so long as we use `func.now()` mapping to
`GETDATE()`. I get this surprising result:
```
CREATE TABLE foo (tz_dt datetimeoffset);
INSERT INTO foo VALUES
('2022-02-04 16:00 +00:00'),
('2022-02-04 16:00 +01:00');
SELECT tz_dt, GETDATE() as now FROM foo
WHERE tz_dt < GETDATE();
```
This returns a result asserting that 16:00 CET is before 15:34 CET:
```
tz_dt | now
------------------------------------------|-----------------------------
2022-02-04 16:00:00.0000000 +01:00 | 2022-02-04 15:34:17.117
```
I assume the datetimeoffset is being converted to a naive value in UTC
(15:00) and then compared.
