mod_mam: Store archives with sub-second precision timestamps Changes sub-second part of example timestamp to .5 in order to avoid floating point issues. Some clients use timestamps when ordering messages which can lead to messages having the same timestamp ending up in the wrong order. It would be better to preserve the order messages are sent in, which is the order they were stored in.
