susumu.yata 2013-03-01 18:07:43 +0900 (Fri, 01 Mar 2013) New Revision: 26896c57c2bba18d93e8b550a6bcf1e4c130dc36 https://github.com/groonga/grnxx/commit/26896c57c2bba18d93e8b550a6bcf1e4c130dc36 Log: Use (now() - from_time_t(0)) instead of time_since_epoch(). Because the epoch of std::chrono::epoch is not guaranteed to be the Unix epoch. I believe time_t is more likely to be based on the Unix epoch.
