Modified: src/main/org/apache/tools/ant/taskdefs Tstamp.java
Log:
Add the ability to specify time offsets when generating time/date property
strings.
Example usage:
<target name="dateformats">
<tstamp>
<format property="now" pattern="dd/MM/yyyy HH:mm:ss.SS"/>
<format property="then" offset="-1" unit="year"
pattern="dd/MM/yyyy HH:mm:ss.SS"/>
</tstamp>
<echo message="now = ${now}, then = ${then}"/>
</target>
Supported units are millisecond, second, minute, hour, day, week, month,
year. The unit is case insensitive
