Description

C# Implementation does not support reading/writing Time32Array and Time64Array which makes it unusable to read/write Arrow batches containing these array types.

 

As the native TimeSpan class in C# only supports resolution in milliseconds, it cannot be used to implement both these types of arrays in a consistent manner. These arrays can, however be supported as simple Int32/ Int64 arrays which represent seconds/ milliseconds/ microseconds/ nanoseconds passed since midnight which the user should parse as needed.
