patch installation jump schedule date

Hi there,

I have scheduled some windows servers to have July - August 2013 patches installed on Feb 1st, 2014 (2/1/2014) at 00:30 AM - 3:30 AM. I just found out to day that these subject windows servers had patches installed from 00:30 AM - 3:30 AM on 12/4/2013 (December 4th 2013) which was the date I set up the update plug-in policy and software update policy.

Would you please advise if ever there was similar incident. It'd really cause impact/trouble for production windows server since there's been patches required reboot (3010).

Thank you,

Charlie.
