Default [Q} Sync app that preserves time stamp?

I'm looking for an app that can sync files between my computer and my android devices. I need it to preserve the time stamp when uploading to Android and I need to be able to select individual folders.
The only two I have found so far are Dropsync (but I don't want to use Dropbox anymore) and Btsync, which didn't run reliable in my setup.
I tried several other ones like Bitcasa, Copy, Foldersync with Google Drive. All of them will the change the date on the Android device to the current one or won't allow to select individual folders.

Any ideas?
