I ran into issue, where I shutdown system with Proxmox before start of EDT, shipped it to co-worker and when he powered it on after daylight saving time was in effect, time was off by 1 hour for Proxmox and all LXC containers. Fix was to re-symlink `/etc/localtime` to proper time zone. Didn't want or cared to dig into this deeper, but interesting to see that there are more issues about this.
