Hi Greg,
Following
http://www.cfengine.org/docs/cfengine-Reference.html#copy
if you specify for copy type=ctime, then you will be fine
I believe
type
Normally cfengine uses the ctime date-stamps on files to determine
whether a file needs to be copied: a file is only copied if the
master is newer than the copy or if the copy doesn't exist. If the
type is set to checksum or sum, then a secure MD5 checksum is used
to determine whether the source and destination files are identical.
If byte or binary is specified, a byte by byte comparison is
initiated. An mtime comparison does not take into account changes of
file permissions, only modifications to the contents of the files.
probably you need to make sure that you keep machines in sync time-wise.
P.S. That is just my guess, I haven't try it yet :-)
