If you're there for a while, you'll need to adapt anyway since your biorhythms will too. But there are plenty of other cases like a reminder to check something after dinner, or my standard wake-up alarm in the morning. Or if I plan to travel, book lunch at a nice place for 1pm, and put it in my calendar I just want it to be 1pm wherever I go, without caring about TZ changes. Calendars, alarms, and reminders have some overlap here and floating time can be good for some cases.
