The Time2 Library is a Java library providing generic time series with configurable time domains. This package provides a few demos.

Version 2.0.0 tracks changes in the Time2 Library t2 2.0.0 and is also more illustrative of basic concepts.

Starting with version 1.0.2, the distribution consists of a binary JAR with compiled classes, of a javadoc JAR and of a source JAR. For version x.y.z:

t2-demo-x.y.z.jar
t2-demo-x.y.z-javadoc.jar
t2-demo-x.y.z-sources.jar

The recommended way is to use git for accessing the source and maven for building. The procedure is easy, as maven takes care of locating and downloading dependencies:

$ git clone https://github.com/jpvetterli/time2lib-demo.git
$ cd time2lib-demo
$ mvn install

This builds and installs the distribution JARs in your local maven repository. They can also be found in the target directory.

When building the software by other means, the following dependencies must be addressed:

• batik-awt-util-<version>.jar Batik
• batik-svggen-<version>.jar Batik
• batik-util-<version>.jar Batik
• jcommon-<version>.jar JCommon
• jfreechart-<version>.jar JFreeChart
• t2-<version>.jar Time2 Library

Versions numbers can be found in the POM file included in the binary JAR:

/META-INF/maven/ch.agent/t2-demo/pom.xml

The following command executes the default demo:

$ mvn -q exec:exec
1896=Athens
1900=Paris
[... some output removed ...]
1932=Los Angeles
1936=Berlin

(Everything after the first line is the output of the command.) The same can be done with:

$ mvn -q -Ddemo.mainClass=ch.agent.t2.demo.Olympics exec:exec
1896=Athens
[... some output removed ...]

A demo requiring arguments is specified like this:

$ mvn -q -Ddemo.mainClass=ch.agent.t2.demo.DateDays \
         -Ddemo.args="1291-08-01 2012-08-28" exec:exec
[1291-08-01, 2012-08-28] = 263367 day(s)

The command computes the number of days between two dates.

Note: this was executed in a Unix shell, which supports line continuation with a backslash. In case your shell or command window does not do this, write the command as one long line.

The source is available on GitHub.

More information on the Time2 Library is available at the project web site.
