Can you change the system date in a Sandbox environment for testing purposes?

We need to simulate running monthly scheduled batch apex jobs over multilple months/year to see mutiple records instances being recaluculed over time.

I can see that there are some comments from 2011 saying that this is not possible but just wanted to check in 2019? I am guessing not but just thought to ask.

Thanks Abdul - this seems fine if you are creating new records where the creation date can be adjusted accordingly, but what if you need to kick off scheduled apex job that will impace multiple records? Is it still possible then?
