To help reduce information available to fingerprinting, we should
randomize the values returned from Date(). I've never thought this was a
useful thing to do before, because Tor latency is high enough and variable
enough that most machines using NTP should be well concealed within the
noise.
However, but bug #1261 brings up a good point about javascript being able
to measure the time intervals of various things (such as typing, but
really it could be anything) to produce a fingerprint.
