This should be selected automatically: UTC unless there is a Windows partition detected at install time.
How to check:
To check current settings for the hardware clock (RTC), do:
egrep "UTC|LOCAL" /etc/adjtime /etc/default/rcS
/etc/adjtime should contain UTC if the hardware clock is set to UTC, and LOCAL otherwise.
/etc/default/rcS should contain UTC=yes if hardware clock is set to UTC, UTC=no otherwise.
How to manually ensure hardware clock is in UTC:
sudo hwclock --utc --systohc sudo perl -p -i -e s/^UTC=no/UTC=yes/ /etc/default/rcS
