Original commit message: [date] Refactor PosixTimezoneCache for different OS Follow up on https://codereview.chromium.org/2740353002. Created PosixDefaultTimezoneCache which is a subclass of PosixTimezoneCache containing definition of LocalTimezone and LocalTimeOffset which is separate for different OS.
