Hello.
I'm interested in "M20 L T" command output (lists files with long file names and timestamps) from different printers/firmwares.
So if you have one then please do octoprint -> terminal -> write M20 L T command and attach output to this thread. Also do the same with M115 (firmware information). Thanks!
Note - at least one file is needed on sd card.
The goal is to have sd card file timestamps supported in octoprint.
Example entries:

I compiled this firmware myself from the LulzBot Git sources with no changes. It looks like the M20 L T output is the same as the M20 output.
'Vanilla' Marlin doesn't support the T parameter to M20, either. It will just respond to the L as normal, ignoring the T.
Ignoring is ok. Error on unrecognized option would be much worse (from adding support to octoprint point of view).
This is Klipper:
