Yes. I will try this.

RFC 1912 define a valueset between 20 minutes and 12h, but I have never
seen a system with values under 1h (perhaps because a few systems
ignores values under 1h).

The bigger problem is, that the webinterface, that the verein use, do
not allow the change of this value AFAIK.

Sincerly,

This is wrong anyway. RFC1912 recommends this range for the refresh
interval of secondary nameservers (for people still using this
ancient concept).

Regarding the TTL for entries, RFC1035 recommends 1 day and down
to 1 hour when needed. There is however no rule which forbids 
values way lower. Lower values only increase load on the nameserver
responsible for the zone, so only one self is harmed by choosing
a very low value.

I prefer this concept, but this is like Linux<>Windows, I guess;)

As I say in the eMail before: It's AFAIK not possible to change the
value in the dnsconfig-website, which the verein use (I use the same
provider for my domains)..
