Paul asked this and I'm posting here so someone who knows better can correct me if I'm wrong ( This is from my notes when I was young)
DATE : Int64 : Milliseconds from Unix Epoch : 1/1/1970 00:00:00 TIME : Int32 : Milliseconds from midnight on 1/1/1970 TimeStampTZ : Int64 + Int32 : (Milliseconds from epoch + Index into list of TimeZones) TimeStamp : Int64 : Milliseconds from epoch Interval : Int32 + Int32 + Int32 : Month + Days + Milliseconds Interval Day : Int32 + Int32 : Days + Milliseconds Interval Year : Int32 : Month A slightly readable version of these can be found in the C++ client :). $drill_src/contrib/native/client/src/include/drill/recordbatch.hpp which has a bunch of 'Holder' structs for the date-time types.
