TZInfo does return an offset of GMT+11 for the Solomon Islands
(Pacific/Guadalcanal) and indicates that daylight savings is not

ActiveSupport::TimeZone maps "Solomon Is." to the Asia/Magadan
timezone (in the MAPPING Hash in
lib/active_support/values/time_zone.rb). Since Magadan is a town in
Russia that observes a timezone of GMT+12, the ActiveSupport mapping
would appear to be incorrect.
