MrHenning opened a new issue, #363:
URL: https://github.com/apache/arrow-julia/issues/363
When opening a table that contains a `Time` object containing `MICROSECONS`
(which I think is the default with `python`/`pandas`) I get an error.
Example:
1. Create `python`/`pandas` dataframe:
```python
pd.DataFrame(dict(
i=range(0,10),
time=[datetime.time(hour=i) for i in range(0,10)]
)).to_feather('~/python_time_df.arrow')
```
1. read file in `julia`:
```julia
Arrow.Table("~/python_time_df.arrow", convert=true)
```
yields the error
```
Failed to show value:
MethodError: no method matching

Defining
```julia
ArrowTypes.fromarrow(::Type{Dates.Time},
x::Arrow.Time{Arrow.Flatbuf.TimeUnits.MICROSECOND, Int64}) =
convert(Dates.Time, x)
```
seems to fix the error.
