Re: touch - cannot use options "backward"

[Alfred M. Szmidt]

   However, I tried several version of touch (coreutils): 4.5.3,
   4.5.8, 5.0, 5.2.1 and this option is not available.

GNU touch has never had this (--backward) option.

   Or is there another program to change the time stamp of a file
   (like 1 hour backward).

touch -m -t MMDDhhmm FILE

Where MM, DD, hh and mm correspond to month, day, hour and minutes
respectivley.

It's all in the manual by the way...
