[GitHub] [arrow-julia] tpgillam commented on issue #327: DST ambiguities in ZonedDateTime not supported

tpgillam commented on issue #327:
URL: https://github.com/apache/arrow-julia/issues/327#issuecomment-1169090020

   The relevant sections of code are:
   
   https://github.com/apache/arrow-julia/blob/532b89b2c5740124cadca632a14ebb6cc9a0dca5/src/eltypes.jl#L273-L274
   
   and
   
   https://github.com/apache/arrow-julia/blob/532b89b2c5740124cadca632a14ebb6cc9a0dca5/src/eltypes.jl#L263-L266
   
   which indeed show that we're currently using an `Arrow.Timestamp` object with _local_ time since the epoch and the timezone.
   
   This is the closest that I could find as to the official specification, which indeed says that the timestamp part should be in UTC:
   
   https://github.com/apache/arrow/blob/20b66c255ff617c438775e54081eaa02d5b983e1/js/src/fb/timestamp.ts#L16-L21
   
   Unless I'm missing something, I think this means that we currently have broken interop with other languages for zoned date times?
