I found several older posts about system time sync and a recommendation here. My KVM setting for current Whonix Workstation is utc
(no random offset) and sdwdate is keeping the VM’s clock in sync.
The problem is the VM is constantly late so the time-sensitive app running on Workstation reports peers’ time is in the future. It’s not by a “lot” (<2s).
This screenshot shows Workstation guest vs. KVM Host:
Tor latency seems to be around 200ms - not sure if that’s a factor here.
I looked at chrony which was discussed years ago, but it seems to conflict with quite a few Whonix-related packages so I guess installing it could break a lot of things.
Any other option to keep Workstation’s system time deviate less, say <0.5s?
