answering my own question: TOUCH
looks like what I want... gotta love BSD Unix...
NAME
touch -- change file access and modification times
SYNOPSIS
touch [-A [-][[hh]mm]SS] [-acfhm] [-r file] [-t [[CC]YY]MMDDhhmm[.SS]]
file ...
DESCRIPTION
The touch utility sets the modification and access times of files. If
any file does not exist, it is created with default permissions.
By default, touch changes both modification and access times. The -a
and
-m flags may be used to select the access time or the modification time
individually. Selecting both is equivalent to the default. By
default,
the timestamps are set to the current time. The -t flag explicitly
spec-
ifies a different time, and the -r flag specifies to set the times
those
of the specified file. The -A flag adjusts the values by a specified
amount.
.....
full definition can be had by typing MAN TOUCH
I hope others can use this knowledge..sorry to raise the alarm.
I'm off to write a handler, which I'll post later if anyone is interested
Now I've got to find those EXIF routines, they're around somewhere....
thanks , self
this is the kind of stuff that LC is so good for...
