Fast time or slow time

In case you didn't know it - Daylight Saving Time ended earlier this morning (2 am). Hopefully you remembered to set your clock back an hour.

And I probably shouldn't even write this, but I just don't understand... What is 'slow time' and 'fast time'? Yesterday someone from our church called the house and asked Jane what time our worship gathering was going to be this Sunday (today). She thought they were kidding, but to be on the safe side she said, "Same as always - 10 am!" And then they asked, "Is that slow time or fast time?" They were dead serious. So she had to explain to them that everyone would be setting their clocks back an hour, and it would be 10 am on "standard" time again.

Now, to be fair, I know hoosiers are new to this. Indiana just started observing Daylight Saving Time again last year, so it's understandable to not have a good grasp of it yet. But I don't know what 'slow time' and 'fast time' mean. I mean, I suppose one is for Standard and one for Daylight Saving Time, but, so, which is which? One is not slower and one faster. Time is time. I just don't get it. Anyway, there's a good article "Fall back: It's finally time to reset your clock" that explains not only Daylight Saving Time, but it also has other useful info about sleep, why we have crust in our eyes in the morning, morning breath, why we snore, and why we yawn.

Good day, all!
