Ant rollbackDatabase rollbackdate doesn't work

I am having some real problems with the rollbackDatabase ant task.    I specify a rollbackdate but no matter what format I specify the date in I get this error

"Can’t assign value ‘2010-12-01 00:00:00’ to attribute rollbackdate, reason: class java.lang.IllegalArgumentException with message ‘null’ "

Here is the ant task

<rollbackDatabase
            changeLogFile="${liquibase.changelog.file}"
            driver="${liquibase.dbdriver}"
            url="${sqlj.url}"
            username="${sqlj.user}"
            password="${sqlj.password}"
            classpathref=“liquibase.classpath”
            rollbackDate="${rollbackDate}"/>

Looking at the java code for this task it seems that it takes a java.util.Date object and ant doesn’t know how to resolve that object.    Has anyone else run into this issue and if so how did you get around it?

I think ant uses your default locale’s date format.  It works fine for me with the format 12/01/2010 00:00:00

I tried that format and it worked.  Thank you.

What command did you run to achieve this. Was you date passed as a parameter in the command line?
