simple tar question

I am not familar with UNIX but I guess this should be an easy task for experts:
I want to find all the files whose last modified time is later than a pre-specified datetime, and 'tar' all these files. Guess I need to use 'find' command, but not really know how to do it :(

Thanks for the help!

touch /starting_path/comparefile -t 0401001200 && find /starting_path -name "*" -newer /starting_path comparefile | xargs tar cf newer.tar --no-recursion

This is really three commands - the first, up to the &&, uses 'touch' to create a file with a particular date and time stamp (here 4/1/2000 12:00), then the "find" command finds files newer than that date (tar has a --newer option but it's less flexible than find), and finally tar tars them up into your newer.tar archive.

Well, 'touch' wants it as mmyyddhhmm, not yymmddhhmm, but to do the former you do

date +%m%y%d%k%M

and to stick that in the 'touch' command, you'd do

touch -t `date +%m%y%d%k%M`

(note the backticks around the date command - it's the key above the tab key - this tells the shell to put in the OUTPUT of that date command, or 0400171358.)

To do the yymm format, just switch the %m and the %y in the format string.  Sometimes you need perl, but I avoid it whenever possible!
