DefaultTTL	ttl	ttl Duration

DefaultTTL sets the TTL for all records in a domain that do not explicitly set one with TTL. If neither DefaultTTL or TTL exist for a record, it will use the DNSControl global default of 300 seconds.

{% capture example %}

D('example.com', REGISTRAR, DnsProvider('R53'),
  DefaultTTL("4h"),
  A('@','1.2.3.4'), // uses default
  A('foo', '2.3.4.5', TTL(600)) // overrides default
);

The DefaultTTL duration is the same format as TTL, an integer number of seconds or a string with a unit such as '4d'. {% endcapture %}
