FWIW, here is a way to extract timestamps from transaction IDs stored with RelStorage. Kai of HexagonIT suggested it. The timestamps should be in UTC.
PostgreSQL: select (tid >> 32) / 535680 + 1900 as year, 1 + ((tid >> 32) % 535680) / 44640 as month, 1 + ((tid >> 32) % 44640) / 1440 as day, ((tid >> 32) % 1440) / 60 as hour, ((tid >> 32) % 60) as minute, (tid & 4294967295) * 60.0 / 4294967296.0 as second from transaction; MySQL: select (tid >> 32) div 535680 + 1900 as year, 1 + ((tid >> 32) % 535680) div 44640 as month, 1 + ((tid >> 32) % 44640) div 1440 as day, ((tid >> 32) % 1440) div 60 as hour, ((tid >> 32) % 60) as minute, (tid & 4294967295) * 60.0 / 4294967296.0 as second from transaction; Shane _______________________________________________ For more information about ZODB, see the ZODB Wiki: http://www.zope.org/Wikis/ZODB/ ZODB-Dev mailing list - ZODB-Dev@zope.org https://mail.zope.org/mailman/listinfo/zodb-dev
