[Owncloud] Usage of system cron

[Mailarchiv]

Hello,

i am using the system cron which tells me to run cron.php every minute.
But it does not tell how the exact command is.

So i run "php /home/user/public_html/owncloud/cron.php". Is that right?
Or do i need to do something else?

I hoped that this cron would sync my Dropbox and GoogleDrive, but i
still have to wait ages till these folders load, so i guess they are
still updated on opening. Is this intended or is the cron not working?

Regards,
Norman
