DST-related test failure.

[kevinmehall]

The following tests pass in Node. They pass in colony when the host time zone is PST, but not when it is PDT. The tests have been disabled in #725, and are preserved here for later analysis.

var d = new Date();
var offset = d.getTimezoneOffset() * 60000;
var offsetMinutes = (offset / 60000 % 60);
var offsetHours = (offset / 3600000 % 24);

d = new Date();
d.setHours(16);
d.setMinutes(0);
tap.eq(d.getUTCHours(), Math.floor(16 + offsetHours) % 24);

d = new Date();
d.setUTCHours(16);
d.setUTCMinutes(0);
tap.eq(d.getHours(), Math.floor(16 - offsetHours) % 24);
