Hello, this is Six Minute English from BBC Learning English, I'm Neil.
And I'm Catherine.
Thanks for making it on time today, Catherine.
Oh, what do you mean, Neil?
Are you implying I'm always late?
Well, punctuality.
I mean, being on time is not your strong point.
But I do always turn up and I never miss the programme.
I just don't want to be early, Neil, and then wait around for you.
Hmm, people's attitude to being on time certainly varies.
And that's what we're discussing in this programme.
How important is punctuality?
Anyway, Catherine, as you're here on time, you're not going to miss our quiz question.
Oh, no, I certainly don't want to miss out on that.
So, what is it?
Well, in 2011, researchers said that an atomic clock at the UK's National Physical Laboratory would have the best long-term accuracy of any in the world.
But how many years would it take approximately for it to lose or gain a second?
Is it A, 138 years?
