Is there any way to determine if my DNS provider actually use the TTL setting I provide?

$dig @ns1.google.com +nocmd gmail.com A +noall +answer
gmail.com. 300 IN A 74.125.235.53
gmail.com. 300 IN A 74.125.235.54
the second column here is the TTL value (300)

is your friend, as Tutul has already said. You should substitute your domain forgmail.com
, and your nameservers in turn forns1.google.com
.
