There are many sources out there for getting global time and timezone information online. Now there's an service getting local time anywhere in the world from the small startup WorldTimeEngine, a service which is both a mashup as well as an API.
Our API directory now includes 61 geolocation APIs. The newest is the Onuma WFS API. The most popular, in terms of mashups, is the Panoramio API. We list 45 Panoramio mashups. Below you'll find some more stats from the directory, including the entire list of geolocation APIs.
ForWhereIAm is a service that offers real-time, short-lived and localised information. Businesses use it as a place to post information they want to share with their customers, and users can visit the site to get information on deals and announcements that are relevant to their specific location. The ForWhereIAm API makes some of this data available to third-party developers.
