Incorrect snapshot timestamps in maven-metadata.xml

(This may be related to NEXUS-1332 as it is on an artifact affected by it)

(Artifact names changed to protect the innocent)

groupId: group.id
artifactId: artifactID.$

{target}
version: 14.0.0-SNAPSHOT
Artifact was deployed with target=main, so we are looking at directory group/id/artifactID.main/14.0.0-SNAPSHOT

The most recent build in this directory is:
artifactID.main-14.0.0-20090106.195709-143.zip

maven-metadata.xml generated by Rebuild Maven Metadata within this directory reads:
<metadata>
<groupId>group.id</groupId>
<artifactId>artifactID.${target}

</artifactId> (I believe this should read artifactID.main instead, see NEXUS-1332)
<version>14.0.0-SNAPSHOT</version>
<versioning>
<snapshot>
<timestamp>6.195709</timestamp> (should read 20090106.195709)
<buildNumber>143</buildNumber>
</snapshot>
<lastUpdated>20090107162705</lastUpdated> (this matches when I last ran Rebuild Maven Metadata in GMT)
</versioning>
</metadata>

This causes the Maven client to go looking for http://mynexusURL/groups/mygroupname/group/id/artifactID.main/14.0.0-SNAPSHOT/artifactID.main-14.0.0-6.195709-143.zip which doesn't exist (6. should be 20090106. instead) and fail.
