When making long blocks (several years), the block log will show incorrect block lengths. For example, all the recent blocks listed here were integer number of years: https://en.wikipedia.org/w/index.php?title=Special:Log/block&page=User%3A127.0.0.1 I believe this may have to do with the function $wgLang->formatExpiry(), but I cannot easily confirm this.
