Strange "TOUCH" problem

On HPUX 11i, when using touch command to create a file 45mins old, I get the following error message:

touch: cannot change times on /tmp/timestamp

Any ideas???

cheers
Bud

type "ls -l typestamp"
It must already exist and not be writable by you.

Hi Bud,

Is there any time(hardware/software) problem. Please check your system.

Thank you

Just to clarify what Perderabo was saying here. He was indicating the cause of the problem, not the conditions under which the touch will work.
