Subject [jira] [Commented] (ARROW-413) DATE type is not specified clearly
Date Tue, 13 Dec 2016 20:34:59 GMT


Julian Hyde commented on ARROW-413:

By the way, Phoenix uses longs to represent dates and not all the code rounds them (d -= d
% 8640000) and it gets tricky. (Who's going to burn CPU cycles rounding a value that they're
99.9% sure has been rounded?!) As a result you're never quite sure whether two date values
have been rounded, and sometimes someone from Moscow writes some data that drifts into the
previous day.
