To maintain precision, to get nanoseconds, we were multiplying our tick count by a billion, then dividing by ticks-per-second. But that apparently isn't such a great idea, since ticks-per-second is sometimes a billion on its own, so our intermediate result was giving us attoseconds. When you're counting in attoseconds, you can only fit about 9 seconds into an int64_t, which is not so great for our purposes. Instead, we now simplify the 1000000000/1000000000 fraction before we start messing with nanoseconds. This has potential to mess us up if some future MS version declares that performance counters will use 1,000,000,007 units per second, but let's burn that bridge when we come to it.
Tor protects your privacy on the internet by hiding the connection
between your Internet address and the services you use. We believe Tor
is reasonably secure, but please ensure you read the instructions and
configure it properly.
To build Tor from source:
