This is one of the great things about a pump. I personally adjust the time on the omnipod which has different basal rates for different times of the day. And then I just bolus normally. If you are using needles, this can be difficult, but not impossible.

Hi Jon, Thanks for your comment. However, I think you may have misunderstood. I want to make sure readers understand that to switch pump time to destination time (immediately) cannot be done in a day if you're moving across large chunks of time.
Here's why:
Jet lag occurs when travelers suffer from disrupted circadian rhythms. When you pass through different time zones, your body’s clock will be different from your wristwatch. For example, if you fly in an airplane from California to New York, you “lose” thre hours of time. So when you wake up at 7 a.m., your body still thinks it’s 4 a.m., making you feel groggy and disoriented. Your body’s clock will eventually reset itself, but this often takes a few days.
The process for a person using a pump and entering a different time zone requires the same approach. So while I too could automatically update with the touch of a button - I shouldn't. My insulin requirements need to adjust to the new time too.
