Comment #2 on issue 255 by [email protected]: better types for time http://code.google.com/p/memcached/issues/detail?id=255
I believe c99 made intmax_t safe for printing/conversions no matter what the platform. This, I believe, helps handle netbsd's usage of 64bit time_t on all platforms.
As far as a potential bug, I think it would depend on the implementation of time_t and be related to settings items to expire way way in the future or having a system with many many years of uptime on items that never expire.
