Hello,
I'm using SCCM 2012 SP1 CU2 to install W2k12 servers. In the beginning of the TS, the BIOS time is changed (+9 hours) (our local time is UTC+1). I've found a similar thread on this issue for SCCM 2007, but I am not able to find if the issue has been fixed. It was confirmed that is was a bug in SCCM 2007. See http://social.technet.microsoft.com/Forums/systemcenter/en-US/ee840a12-20f7-4cfc-8c5f-ad01dc351782/bios-time-change-by-tsmbootstrap-process-10-hours-difference?forum=configmgrosd
See smsts.log below
