If the item TTL is more than 30+ days (e.g. 960 * time.Hour) Put operations succeed but Get operations fail (item not found). I think there is a bug in the implementation. AFAIK on memcache protocol any duration higher than 30 days is interpreted as a unix timestamp date so I guess the library[0] should check and make the conversion.

Thanks for the report. Would you mind adding an issue to the tracker, along with a small example that fails for you? IIUC, we are already doing the conversion to unix timestamp but there might be a bug somewhere along the way.
