The reason Git doesn't do this is pretty simple: make and various other tools do rebuilds depending on timestamps. If I create a branch off master and make some commits, then switch back to master, I will want the changed files to have their timestamps updated to be newer so that a make on master will rebuild dependencies based on those files. If I set the files to the commit timestamp, those files would be set to the timestamp of master, which is older than my new branch, and make wouldn't work properly. There are some cases where people want the behavior you requested, such as for reproducible builds, and in such cases, you can use a post-checkout hook to set timestamps with touch. -- brian m. carlson: Houston, Texas, US OpenPGP: https://keybase.io/bk2204
