Hi,
The assign task is already defined for you as part of the
AntXtras antlib. The easiest thing to do is to load the
entire antlib and experiment. *See the Quick Start and
User Guide for additional information*.
Example (assuming at least Ant 1.6.5, and AntXtras bin download
to some local directory '${antextensions.d}/antx'):
[Top-Level]
<path id="antx.classpath">
<fileset dir="${antextensions.d}/antx">
<include name="lib/*.jar"/>
</fileset>
</path>
<taskdef resource="com/idaremedia/antx/install/antlib.xml"
classpathref="antx.classpath"/>
[In any target or macrodef]
<assign var="duration" value="now"/>
...
<assign var="duration" value="-now" .../>
...
