Time scale tickFormat broken by latest Chrome version?

[jheer]

To replicate:

var s = d3.scaleTime().domain([-7506057600000, -4213184400000]).range([0, 500])
s.ticks().map(s.tickFormat());
// actual: [ ":00", ":00", ":00", ":00", ":00", ":00", ":00", ":00", ":00", ":00" ]
// expect: [ "1740", "1750", "1760", "1770", "1780", "1790", "1800", "1810", "1820", "1830" ]

In previous versions of Chrome, this produced the expected output (which is what Safari and Firefox still produce). It looks like Chrome is arriving at formatSecond rather than formatYear within the time scale tickFormat method...
