Directory time stamps after file system import, correct on disk, incorrect in nextcloud


following issue:
– transferred a large file tree into the nextcloud data directory directly via ssh terminal
– the time stamps on all files and directories are correct (verified by viewing them in the terminal)
– the files were then scanned with the OCC tool
– result: within the nextcloud web interface, the file time stamps are correct, however the directory time stamps are all incorrect and reflect the time of import via the OCC tool.

Question: is it possible to achieve correct directory time stamps within nextcloud? (on disk, the time stamps are correct but deviate from the time stamp shown in nextcloud webinterface)

running nextcloud version 16.
