@candiduslynx Can you provide me with some explicit sample code that shows
this issue?
When testing this against `main` on the Arrow repo I'm unable to replicate
the issue you're seeing, see below:
```go
func TestReadWriteTimestamp() {
mem := memory.DefaultAllocator
fld := arrow.Field{Name: "ts", Type: array.FixedWidthTypes.Timestamp_us}
sc := arrow.NewSchema([]arrow.Field{fld}, nil)
bldr := array.NewRecordBuilder(mem, sc)
defer bldr.Release()
tsbuilder := bldr.Field(0).(*array.TimestampBuilder)
tsbuilder.AppendValues([]arrow.Timestamp{123450000, 567890000}, nil)
rec := bldr.NewRecord()
defer rec.Release()
tbl := array.NewTableFromRecords(sc, []arrow.Record{rec})
defer tbl.Release()
// tbl schema column 1 has "UTC" for timezone!
var buf bytes.Buffer
err := pqarrow.WriteTable(tbl, &buf, tbl.NumRows(),
parquet.NewWriterProperties(parquet.WithAllocator(mem)),
pqarrow.DefaultWriterProps()))
if err != nil {
panic(err)
}
rdr := bytes.NewReader(buf.Bytes())
out, err := pqarrow.ReadTable(context.Background(), rdr,
parquet.NewReaderProperties(mem), pqarrow.ArrowReadProperties{}, mem)
if err != nil {
panic(err)
}
defer out.Release()
fmt.Println(out)
}
```
I get the output:
```shell
schema:
fields: 1
- ts: type=timestamp[us, tz=UTC]
metadata: ["PARQUET:field_id": "-1"]
ts: [[123450000 567890000]]
```
Note that it still has the UTC for the timezone in the table that I read out
from the file. What version of arrow/parquet are you using? Are you
writing/reading the table differently than in my example above?
