Substance of Code

Analog Clock Service is a service for providing analog clock images to web (or other) applications. Clock Service API let’s you dynamically create images of an analog clock.

Clock Service is a simple servlet implementation that generates an image with the specified parameters. API can be used to define image size (s=100), timezone (tz=zone), title (t=Helsinki) and 12h/24h format (f=24). With this I can use the following URLs to produce three different clock images for three different timezones.

/clockservice/clock?tz=America/New_York&s=150&t=Atlanta&f=12
/clockservice/clock?tz=Europe/Helsinki&s=150&t=Helsinki&f=12
/clockservice/clock?tz=Australia/Sydney&s=150&t=Sydney&f=12

If you would use these URLs with HTML IMG tags then the results would look like this:

These images aren’t created dynamically as I don’t have any public servlet container available.

You’ll need to run this service in a servlet container such as Apache Tomcat, GlassFish or JBoss.
