Yeah, I find it easier too. Having spent decades getting up at every hour of the day or night to go to work. It is just easier. And unambiguous.
And I'd be happier if the entire world stuck to GMT the whole time. I don't get why people just can't get up at different times. But instead have to cycle their days by some arbitrary time like 07:00, to get up by.
Is this what passes for British imperialism nowadays?

That has more to do with sunrises and sunsets than anything else.
