It surprises me that we see these issues even with UEFI, which seems to include support for timezone and DST information [1]. I can confirm this myself, I have UEFI with Fedora 21 and Win7 at home, and I noticed that there seems to be a fsck running on every Fedora boot. I haven't had time to debug it properly yet, but it doesn't seem to work properly out of the box. Moreover, if I look into `journalctl -b`, I see time shifted during the boot process (which kind of messes up the history whenever I search in it). I haven't reported any bug yet, but there's certainly something not working out of the box there.

Zbigniew, do you have any idea why this wouldn't work well with UEFI firmware? Shouldn't the whole problem become obsolete with UEFI? Thanks.
