sdwdate: Secure Distributed Web Date
sdwdate - Secure Distributed Web Date - in Whonix

Do sdwdate issues impact anonymity?
sdwdate failing doesn't mean deanonymized.
Even sdwdate does not work, there's still Boot Clock Randomization
To put it into perspective, Tor Browser Bundle on the host operating system (unrelated to Whonix) have neither sdwdate nor Boot Clock Randomization.
The time of sdwdate issues matters. If sdwdate fails
- A) during its first run after boot then that's worse than,
- B) sdwdate failing during any subsequent runs.
The latter is only for time keeping in long running VMs. For example, if sdwdate succeeded after boot but then would only succeed once per day in long running VMs that might still be good enough.
Planned sdwdate-gui enhancements include:
- Only showing sdwdate failure if sdwdate failed after boot and multiple times in long running VMs.
- Making Tor log output (
anon-log) more accessible. This might help to redirect the often misplaced attention on sdwdate to Tor.
