A reply to my feature request at LAME-dev:
But in any case it is rather trivial to add that step to the frontend
application (Audacity in this case). The advantage: In Audacity, the
functionality should be generic, you would be able to preserve timestamps
(propagate from input files or keep the one of an existing output file) for
any output format, not just MP3 via LAME.
It would be much more powerful to have such a feature in the frontend.
Also, thinking of the variant that you want to keep the time stamps of
input files (re-reading the comments, I guess that is what you want) …
are we talking about using Audacity to auto-convert a large collection of
WAVs (or whatever) to MP3? Does it have a batch functionality?
If not, I would also under windows strongly recommend using a shell like
Cygwin … it’s so much more fun to automate tasks. Anyhow, let’s consider
you use Audacity … if you have an input file and work with it (cutting,
effects), then want to export with LAME; In that case, LAME gets fed an PCM
stream, not a file (I suppose) … it has no way of knowing the timestamps
of any original input file, so this feature would be impossible!
(Disclaimer: I’m just giving my opinion here, I am not actually working on
LAME. So if you feel annoyed by my persistence about not adding such
functionality to LAME, don’t be angry at the LAME project people;-)

The majority of users has Windows, so the below commands do not work. THe
files have different timstamps, so one cannot change them recursively to
match. It would be very helpful, Windows frontends like Audacity would
support this feature.

This was the description for Audacity. For LAME, a commandline option
“–preserve-filedates” could be used.
Many have Gigabytes with old wave/other audio formats to be converted.

You can respond by visiting:
Summary: Option to preserve the file creation + modification date in
having many old files which require sorting by date.
I need to retain the file creation and change dates, so an option/checkbox to select this would be very helpful.
This is a common request (3489332 Add encoding option to maintain file modification time Open 2012-02-19 nobody jmcatee 5 ) and easy to implement and would maintain compatibilty,
