And how whould puppet know what you consider "an actual change". You
specified that the actual systemtime should be in the first line. Since
it's not true on your client, puppet will change the file (cause
checksums are different).
Or to put it this way: Imagine puppet distributed the file with an actual
timestamp. Someone now opens the file and change the timestamp in your
header. What do you expect puppet to do now?
If you really depend on your headerline consider the following: Don't
use Time.now but use something like
File.stat('/etc/puppet/modules/snmp/template/snmp.conf.erb').mtime.gmtime
[Maybe theres a way to address the filename from the template itself,
but I havent figured that out; __FILE__ and ARGV are not working]
This will be the same in every puppet run (except you changed the
template). But if you assign your class to a new node, the header will
still reflact the time when you changed the file on your master, and not
when puppet installed that file on your node.
