Reverting reverted r17148 and fixing build (test) breakage by side stepping the Windows vs. Linux issue of different Date object for the same millisecond time stamp.
We do that by using UTC Date methods (they eliminate DST problems).
Windows:
new Date(129193200000);
Sun Feb 03 1974 23:00:00 GMT-0800 (Pacific Standard Time)
Linux:
new Date(129193200000);
Mon Feb 04 1974 00:00:00 GMT-0700 (PST)
