Github user rip-nsk commented on a diff in the pull request: https://github.com/apache/orc/pull/265#discussion_r186487106 --- Diff: c++/src/Timezone.cc --- @@ -710,7 +710,11 @@ namespace orc { * Get the local timezone. */ const Timezone& getLocalTimezone() { +#ifdef _MSC_VER + return getTimezoneByName("UTC"); --- End diff -- http://unicode.org/cldr/data/common/supplemental/windowsZones.xml - here is a mapping of windows <=> *nix time zones, and here - https://github.com/google/cctz - "timezone" library which probably is a best choice (BTW https://github.com/google/cctz/issues/53). Anyway, it is non trivial work which I think does not related to orc directly. I believe it should be customer decision how to pass/extract timestamps from orc library and any timezone conversions should be done on customer side.
