I can't help you with the issue at hand, but I want to point out an error that the following is wrong:

ctime is the Unix timestamp representing the object's creation time. OP sets this when saving an object for the first time.

"c" stands for "change", not "creation". It's the time of the last status change

The field st_ctime is changed by writing or by setting inode information (i.e., owner, group, link count, mode, etc.).

$ touch a

$ perl -MFile::stat -wle'print "".localtime( stat("a")->ctime )'
Fri Aug 21 13:31:40 2009

$ sleep 2

$ perl -MFile::stat -wle'print "".localtime( stat("a")->ctime )'
Fri Aug 21 13:31:40 2009

$ chmod go= a

$ perl -MFile::stat -wle'print "".localtime( stat("a")->ctime )'

Also, the module name is awful, and I have no idea what the module does after reading the Description and Synopsis.
