How long does it take for Golden Whistlers to attain adult plumage?

I watched a male Golden Whistler for several minutes this afternoon. It was a very scruffy Individual which caused me to wonder if it was an adult moulting, there was something wrong with it (which there didn’t seem to be.) or if it was a young bird attaining adult plumage. Does anyone know how long this latter takes? (This is a time when a photo could be helpful on the site.)
