Tor seems to be reading from two different time sources in a macOS VM
I started chutney (and its tors) a few minutes after resuming from sleep, but Tor sometimes gets the time wrong by 15 hours. (Which is approximately the time the VM last slept.)
I wonder if we're using the wrong macOS time APIs? Or it could be a VM or macOS issue.
