It cannot automatically apply the 30W rule, as it doesn't take your location into consideration. If you're East of 30W, call it with the -e option and it will yield the correct results.

Any problems or issues should be mentioned to Zigdon either on the wiki or in the [#geohashing channel on irc.foonetic.net], as well as posted at Talk:Implementations.
