Loads of websites refuse to load on my MacBook because it tells me their security certificate is out of date, including this very one. Obviously accessing it on my phone is no problem or I wouldn't be writing this.
Why is this happening? My date and time are set correctly so what else could be the problem?

Anyways maybe your browser needs a security update installed?
It's not something odd like the wrong date set on the macbook is it? I know it's very unlikely to be the case but worth a check. Or try a different browser?
Have you tried using Drac's iPad?
Is it an old MacBook? Try this..

Is your OS up to date? I believe 10.12.1 оr lаter should be OK. There were some issues in Safari recently which required manual fixes but have now been sorted out in 10.15.7 (which is the latest OS by mid-2012 MacBook will accept).
This use to be something I’d regularly suffer with MacBook, I can’t recall how to fix but it would only last so long.

It’s actually one of the reasons I started using my iPad more than the MacBook.
@john_l How do I fix DST root CA X3 expires on Mac.
Many thanks for the tip, I did just that and it's now resolved the problem.
Excellent! I can't claim the credit for it, top tip from a friend when mine started doing the same thing.
Once again the forum has come up trumps for me.
Just popped in for a quick browse and spotted this thread.
My 2007 vintage MBP is on OS 10.11.6 and won't update to anything later. Chrome was giving me that trusted cert message on an increasing number of sites, STW included.
That fix up there ^^ has sorted it.
Result.
I can put some meat on this.
Certificates work on a "web of trust." You trust a website certificate because someone else told you it was good.
Like, why do you trust driving licences? Because they're issued by the DVLA, and you "know" that the DVLA is a trustworthy central source. If I gave you a bit of paper and wrote "Driving Licence" on it, not so much.
In the browser world it's the same. A website says "this is who I am" and your browser knows to believe it because... how? Because that cert was issued by a trusted source just as above.
Where does that trust come from? Root certs. A root cert is something installed into the browser that says "we can trust the DVLA" so when you rock up with your driving licence your browser believes you.
Sometimes, root certs expire before the browsers have caught up, and shit starts to break left and right. You can install root certs manually - which I expect is what the above fix does - but typically they're included with your browser and refreshed with Windows Update / browser updates / whatever the Mac equivalent is.
This specific fix for this specific root cert ^^ won't always work, but the concept generally almost certainly will. You should be able to drill down into a broken certificate chain (typically a padlock icon in the address bar) and see what's wrong.
Certificates work on a “web of trust.”
I know you know what you're talking about but PKI (which is the basis of web-site certs) isn't a web of trust, it's more a chain of trust - a web of trust refers to decentralised trust [pedant mode off]
Yeah, you're right, good catch. That was a slip of the brain, it didn't feel right when I wrote it but it was 1am... (-:
