no timestamps are provided in the log files

I know that in the default server configuration there are no server logs but after adding additional options so that as an administrator i must have full insight into the logs (simpy add log /var/log/openvpn/openvpn.log and log-append /var/log/openvpn/openvpn.log to server.conf) I noticed that there is no specific date in the log files /var/log/openvpn/openvpn.log (no timestamps in log files)

OpenVPN connection use systemd so after that i figure out that when i edit service

`sudo nano /etc/systemd/system/openvpn-server@.service`

and remove --suppress-timestamps after i restart openvpn-server timestamps are now provided in the log files.

Anyone who analyzes logs would rather know the exact day or time the error occurred, so I think this should also be corrected when service is creating.
