 configuration, a set of functions are available globally for use in _any string_
 in Packer templates. These are listed below for reference.

+* ``isotime`` - UTC time in RFC-3339 format.
 * ``timestamp`` - The current Unix timestamp in UTC.

+Specific to Amazon builders:
+
+* ``clean_ami_name`` - AMI names can only contain certain characters. This
+  function will replace illegal characters with a '-" character. Example usage
+  since ":" is not a legal AMI name is: `{{isotime | clean_ami_name}}`.
