Have you the time?

I have never stressed more over
The loss - or is it the gain? - of an
Hour. Fall back. We give away a
Bunch of them when we travel.
Those timezones cost, and pay
For the pleasure of meeting a
Daring Frenchman or a dashing
Brit. After our trip, we fall into
A different time. It's not ours, it
Is theirs. Are we in Rome! Oh my,
What time is it? I've lost track.
