In the UK, GMT is often used to refer to "the current British time" both GMT/BST. I've seen the same in the US where people say EST but mean EDT.

Whenever someone says GMT/PST/EST during the summer, I need to ask them to confirm whether they mean BST/PDT/EDT.

Whatever I assume, I might be off by an hour.

Is it? I mean, I'm British and I'm not aware of this.

I've seen a few people do it, but it's also usually corrected as been wrong.
