Out of sync means that the Windows API UTC time on your PC is different to the server UTC time. If the server time is correct, maybe it's something with your PC? Can you check if the local time zone is set up correctly?
I turned on 'Automatically adjust clock for DST' and fixed one hour offset that happened as a result and it seems good now, no more "Out of sync" message.
The thing is, this is a virtual machine and the host is already adjusting the clock per DST rules, so I had that checkbox turned off. But, it confused Zorro, although the time was OK, but some calculation that depends on the timezone and/or DST status failed, obviously.
I'll see what I can do with the configuration on the host, although I somehow liked it this way (guest machine doesn't deal with time, just uses what the host provides, and host is prefectly synchronized).
