Comment 4 for bug 51409

> 3. also no way to select RTC in GMT or UTC.

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
