No idea, especially since you don't provide a context, and the question isn't phrased correctly. Is that the EXACT question, and exactly how it's written, because in English, that doesn't make grammatical sense.

If you mean you want the date of a file to be two months in the past, then you need to read the man page on the touch command.

that sounds like you are doing something like a RH033 Basic Essentials Course...
If that's the case have a read in your provided papers but always remember: there is more to read (man pages, books, online stuff...)

but that means you have to workout what the date was 2 months ago..

date --date='-2 month'

I'll let you workout how to get that into the touch in the appropriate format

man date
and

Well, a time stamp of 2 months back means exactly that: the date that it was two months ago. Just like "three days back" would mean three days ago, etc. Simple.

...and a brief search would tell you that the "CC" means the first two digits of a year, which are optional.

Most of your questions seem like verbatim homework assignments, and show very little effort of your own.

It was not a guess, and you could easily have found all this out, had you tried to research any of it on your own FIRST.

It was a stupid question and a stupid answer written by a stupid teacher. If they were trying to teach you how to use the help system then they obviously failed miserably. Someone might want to recover the file as it was before 2 month worth of stupid changes but in the real world you'll probably only use touch to create an empty file.
$ touch stupid.txt

You have to understand that many people just come on here and ask direct questions, without first doing proper research.
The fact that your question is obviously related to some course and appears to be an "end of chapter exercise" is worrying, and "annoying"

Really you need to go back to the beginning and work through the book again.

if you are ever stuck with a command ( even if not, worth a look for the extras )
command --help ( sometimes -h or -help )
man command
info command
websearch : " command tldp " ( other things to include are linux bash shell )
tldp is "The Linux Documentation Project"

When you ask a question, give a little background
show what you have tried, what you expected and how the results are not what you expected.

show sample data that represents any input, and what output you want from that.

and don't get angry because someone got angry because they thought you were being lazy


looking forward to your answer to the question in OP
