Just a Heads-Up:fired up my first test install of Leap 15.2 in a dual boot laptop with Win*, so System clock is expected to be set to local time.
I checked the CET time zone, system clock to UTC NOT checked, network was configured so the installer checked with ntp3.opensuse.org (or something like that, too quick to write down...) and on first reboot I find myself...
in what is apparently the US Eastern time zone, 6 hours earlier than local time.

Minor quirk to be sure, but if other dual-booters (out of the US EST zone) confirm, maybe we have found a glitch in the installer.
