You don't have to wake up at the exact same time everyday. As long as you wake up within a few hours of the same time, no problem. Important is measuring the minute you wake up so that it can record your basal temp and that you measure everyday. If you skip days, you get more red lights (red light = no sex unless you want to get pregnant). If you are sick or exhausted, don't measure - this has only happened once to me in a year. I have not crossed major time zones with it, but they write about that in their manual along with how to handle it if you work different shifts (one daytime shift, then a nighttime, for example).
