New Zealand Question Update

<p>Found this on multiple grammar sites: </p>

<p>‘When’ means ‘at that moment, at that time, etc.’. Notice the different tenses used in relationship to the clause beginning with when. It is important to remember that ‘when’ takes either the simple past OR the present – the dependent clause changes tense in relation to the ‘when’ clause.</p>

<p>So in the 1960s or the specific year, can't remember which, musicians began to reach an international audience. AT THAT TIME, 1960 or whatever year it was, musicians began to reach an international audience.</p>

<p>when needs to be changed to that for sure. It’s a structure like not only… but also. It was not until… that. However, I think there is a question about whether “had changed” was an appropriate tense usage.</p>
