How much time will pass on Earth if you fly to Jupiter and return?

Recently, in a discussion, we were asked:

How much time will pass on Earth if I, for example, fly to Jupiter and return?

Currently, technology does not allow us to carry out a manned flight to Jupiter, but let’s imagine what it would be like if we did fly to Jupiter. What problems and difficulties would we face? And most importantly, how long would this journey take?
