Amend File Without Changing Timestamp

Hi,

Is it possible to amend a file without changing the last modified date?

If it is, how do you do it?

If it's not, is there a way to create an empty file with the same timestamp as another file?

I know you can use touch -t yyyymmddhhmm.ss filename but, I would want the file to have the exact same timestamp as another file.

Any help would be greatly appreciated.

Thanks

****EDIT****
Sorry, I forgot to mention. I'm trying to script using bash.
