Also find time zones by short name and offset name
Display country results by region name (country name and comment if applicable), and for countries having multiple time zones (e.g. Mexico), show all of them
Display abbreviation results together their long name to disambiguate (e.g. "Pacific Standard Time (PST)" instead of "PST"), and for abbreviations having multiple time zones (e.g. PST), show all of them (BUG: 462836)
For date matches, show difference to local date
For time matches, display date difference as "+/-1 d" if applicable and none otherwise, instead of always displaying full date
Sort results by relevance based on match length and index, so that e.g. with query "gmt+1", "GMT+14" wouldn't be higher up than "GMT+1"
Find and display time zone names with " " instead of "_"
