> You can map the cols in question to these types explicitly in the conversion options via `column_types`: https://arrow.apache.org/docs/python/csv.html#customized-conversion That's what I tried first but it doesn't work because that requires a [csv.ConvertOptions.timestamp_parsers](https://arrow.apache.org/docs/python/generated/pyarrow.csv.ConvertOptions.html#pyarrow.csv.ConvertOptions.timestamp_parsers) strptime(3) format string and there isn't one afaict for Unix timestamps in integer format (the strptime in Python does have one for Unix timestamps at second resolution but that isn't available in the C version - https://github.com/apache/arrow/issues/39839#issuecomment-1915981816 - and even if it were I need millisecond and nanosecond). Or am I missing something? Do you have working example code? I'm also wondering whether there is a way to apply the cast conversion during csv_read. -- This is an automated message from the Apache Git Service.
