rsync --time-limit=120 (or any other number) 'unknown option' ???

when I set up an rsync job in OMV GUI with extra option --time-limit I get an error message in the email notification like this:

rsync: on remote machine: --time-limit=238: unknown option
rsync error: syntax or usage error (code 1) at main.c(1551) [server=3.0.9]
rsync: connection unexpectedly closed (0 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(235) [sender=3.1.2]

When I run an rsync job locally on my Ubuntu PC with this option it's no problem. Rsync versions on PC and OMV box are the same > 3.1.2

The cron job on OMV seems to be OK:

rsync --verbose --log-file="/var/log/rsync.log" --rsh "ssh -p 22 -i '/etc/ssh/openmediavault-2d26a655-541b-4817-bee8-16a07f5f491d'" --recursive --times --archive --delete --perms --time-limit=238 '/srv/dev-disk-by-label-RAIDVOLUME/Backup/ANTEC4100/' 'username@rsync.hidrive.strato.com:/users/username/UBUNTU' & wait $!

Is this because a local rsync job behaves different from an rsync job to a remote server?

Both my Ubuntu PC and OMV are based on Debian and rsync between those is no problem with that option.
So, my guess is that the remote server, which uses rsync version 3.0.9 does not support it.
But I can' t find anything about it in the release notes at http://www.rsync.samba.org.

I have contacted Strato (remote server provider) about it, so I hope they can solve it.
