As of now, there is no such option to only overwrite the file based on a timestamp check. You can force overwrite as a work around with the -f , --force option to avoid throwing an error and aborting your script. This will not help with avoiding the extra time to extract your files. That would require an extra option that does not currently exist. If you have time and want to contribute this feature, it would be considered. Unfortunately, it is not a priority so I am not planning on working it anytime...

Hi! Thanks for including the patch. The patch you linked modifies the config.sub file, which is generally against best practices. The config.sub file is maintained and released by autotools. Using CMake may solve your issue, but it is somewhat experimental on non Windows MSVC for liblzma. The next alpha release should happen in February and it will have some patches to CMake. I don't believe the next release will have the config.sub patch you are proposing, especially if you can use autogen or CMake...

Hi! Just to clarify, are you looking for a command line option to check if the modification date / creation date on (filename).xz is newer than the modification date / creation date on (filename)? As of now, there is no such command line option to accomplish this, but it would be straightforward to wrap xz in a script to test for this.
