You mean in the ivy file of the module C  <info organisation="MyCompany" 
module="C" ... publication="xxxxx"  >
No, or I should change this date each time I publish and I've got a 
nightly builder ...

After publication in the repository the ivy file created was 
myrepos/MyCompany/C/ivy-1.0.0.xml (following my ivy artifact pattern)

<?xml version="1.0" encoding="UTF-8"?>
<ivy-module version="1.0">
  <info organisation="MyCompany" module="C" revision="1.0.0" 
status="integration" publication="20070223132315"/>
...
</ivy-module>

A publication date is set ... I thought this date was used ?
