Purge Nexus Timeline task calculates wrong purge "window" days

The "purge" operation of Timeline in NX2 calculates wrongly the "days" parameter, making the "window" much bigger then parametrised (taking it's square more precisely). The persist part does the purge well, but the Lucene index will contain way more records than it should.

After persistor is invoked with "days" to purge, indexes – that uses millis instead of days as input parameter – is invoked like this:

indexer.purge(0l, System.currentTimeMillis() - (days * TimeUnit.DAYS.toMillis(days)), null, null);
