we found this issue to many file in my owncloud but if I deleted and upload again it with show the correct modified date

PHP version: 7.0.33
ownCloud version: 10.2


this looks to me quite old. Maybe you could update to a more recent version like 10.4.1 and try again if this is already solving your issue?

I also think that this topic doesn’t belong into the “Desktop” category as it seems that you don’t have a problem with the Desktop client.
