Time conditions bug?

Hi,

I recently upgraded from FreePBX 2.10 to FreePBX 2.11 along with upgrading CentOS to 6.4 and Asterisk to 11.5.1 on the way. Everything seems to be fine except the time conditions are now working the opposite way before, i.e.

I have a time group to forward calls outside work hours to a different number using the following time group:

17:00-09:00|fri-mon||
17:00-09:00|mon-tue||


and so on. When I set the destination to be the out of hours number when this time group matches, it actually forwards the calls during work hours which is the opposite to what I would expect.

Obviously I can just switch the conditions around for now but am wondering if it’s a recently introduced bug?
