The issue with XEP-0256 (and XEP-0012) is that it is fuzzy by only including a 'seconds' value, which could be further coupled with a <delay/> element. XEP-0319 does the simple thing and just states the timestamp that the user went idle. No need to try and calculate that time based on seconds, stanza arrival times, and delays. That simplifies the work needed by both clients generating this data & those receiving it. It's possible for a server to translate the XEP-0256 data to the XEP-0319 format, see http://hg.prosody.im/prosody-modules/file/ae1d7665cde9/mod_idlecompat/mod_idlecompat.lua — Lance
