9266f7497futil: Use std::chrono for time getters (MarcoFalke)3c2e16be22time: add runtime sanity check (Cory Fields) Pull request description: I have a followup that should remove the last of our `boost:posix_time` usage in `ParseISO8601DateTime`, but that will likely need more cross-platform testing/discussion, so have just split them up as this change is straight forward.
