Those two functions fundamentally perform different operations so your question doesn't make much sense. What are you trying to solve that leads you to ask this question?
If you are refering to the output of the functions, the answer is no -
Get Time returns a timestamp, which is absolute time, obtained from the OS (with ~16 ms resolution, at least on Windows).
Wait returns the value of the ms timer, which starts at 0 when the computer is turned on and is incremented every ms. It's also reset after about 49 days.
