Month '17' out of range

  I've just added a new agent to our EM12c install and on the Agent Page it shows a Matric collection error.

In the Metric Issues the error message being shown is :

oracle.sysman.emSDK.agent.fetchlet.exception.FetchletException: Month '17' out of range 0..11 at /u01/app/em12c/core/12.1.0.2.0/sysman/admin/scripts/hostOSD.pm line 1911 

line 1911 in that script is:

$l_epoch_sec = timelocal($sec, $min, $hr, $dd, $mon, $yr);

It all works fine on other boxes so all I can assume is that for some reason on this box the date format is being returned differently.

Has anyone else experienced this and if so how did they fix it.
