Timestamp not preserved when rsyncing to SMB share on macOS
I am using rsync 3.2.7, installed via Homebrew on macOS Ventura 13.2.1. Apple Silicon, if it matters (Apple M1 Pro).
rsync --archive does not set the timestamp correctly when the destination is a mounted SMB share.
When syncing to a local filesystem directory, the timestamp is copied correctly.
Also when I switch to the builtin macOS version 2.6.9, it does work correctly as well.
Repro steps
Create test file:
$ echo helloworld > test/asdf
$ touch -t 202301010000 test/asdf
$ ls -l test
total 8
-rw-r--r-- 1 dliu staff 11 Jan 1 00:00 asdf
Sync to mount, timestamp not preserved:

I think I'm running into this issue as well. I noticed it while syncing data from my iMac using rsync 3.2.7 (installed via Homebrew) on macOS Ventura 13.2.1. I am mounting an smb share and running the following command:
rsync -rltvzhP ~/folder/data/ /Volumes/tank/differentfolder/olddata
Running the above command successively will re-sync everything I've just transferred. The modified date is not being being honored or carried over, but rather being updated to the datetime that the current rsync command is carried out. The details of my SMB connection as reported from my Mac to an Unraid share:

Edited to add new information.
If I run rsync with -vvv it looks like it is setting atime to the current datetime. It seems to me that both modtime and atime should be the same as the original file, yes?
