Does UNCalendarNotificationTrigger fire at the same time everyday even if user changes his timezone ?

I am using UNCalendarNotificationTrigger and from my initial tests with simulator and timezone changes in my mac i see that notification donot get triggered at specific times if timezone changes, is this expected behaviour ?

Does UNCalendarNotificationTrigger fire at the same time everyday even if user changes his timezone ?
