Phil,

I'm writing a Perl script to update a bunch of tags in some images. I know the -P can be used on the command line to preserve FileModifyDate but I can't work out how to achieve this in a script?

It's not so pretty, but here's how you do it in a Perl script:

Code:

my $modTime = $^T - (-M $file) * (24 * 3600);
my $accTime = $^T - (-A $file) * (24 * 3600);

[ ... process file here ... ]

utime($accTime, $modTime, $file);
