I'd like to suggest that anyone who says Copilot saves them time is an indication that they're not doing their job, ie accepted the code without taking the time to think through each line and its implications.
To properly review code, you have to consider for each variable, each expression, whether it's appropriate, how it interacts with the rest of the program, etc.
Since you didn't author the code I'd say this should take more time than if you wrote it yourself.
