Review Comment:
```suggestion
Set the value of isAdjustedTOUTC when writing a TIME column.
If True, this tells the Parquet reader that the TIME columns
are expressed in reference to midnight in the UTC timezone.
If False (the default), the TIME columns are assumed to be expressed
in reference to midnight in an unknown, presumably local, timezone.
