The funny thing is I am already at an early riser, being on time is not hard for me. I know adjusting into different time zones can be challenging, but just as long as you know what time zone that you should be doing for work in general, you should be able to keep up with the time zones that you are currently and presently working with. I'm up early and I'm up, so I don't think the time zones will be challenging at all, but you just have to make sure you're prepared for each time zone that is available for you, or making sure that you're aware of that time zone that you're working with.
