If I set other servers as fallback like for example "ptbtime1.ptb.de 
ptbtime2.ptb.de" the result is the same.
But if I set the "NTP=" setting then this setting is respected. Only 
"FallbackNTP=" is not working.

The system is running network-manager and there are no manual network 
settings. DHCP is not announcing any time servers.

Please tell me if you need more information and how I should provide it 
if necessary.

Best regards,

Marcus Jodorf
