In Cyberduck and Mountain Duck, the date created field is reported as the date modified field rather than the date modified field. This means that you cannot use synchronization software which depends on timestamps, such as FreeFileSync. This is not a defect in Cryptomator in this case, as opening the same vault in Cyrptomator from OneDrive Files On-Demand in Windows 10 produces the expected result. A comparison image and the version numbers tested are attached. As an example, the first file (3.8MB) was added to the vault on 12/6 but was actually last modified on 11/27
Currently modification dates of files uploaded to OneDrive are not preserved regardless of the Cryptomator vault. For other protocols, make sure to have Preferences → Transfers → Timestamps → Uploads → Preserve modification date checked.
Thanks for pointing out.
Reported dates were those of OneDrive keeps internally for creation and modification dates. We have performed necessary steps to implement the timestamp feature for OneDrive component.
