REGRESSION(r120552): Many tests timing out on Windows
https://bugs.webkit.org/show_bug.cgi?id=89433
Reviewed by Andy Estes.
* wtf/CurrentTime.cpp:
(WTF::lowResUTCTime):
It looks like there were two bugs:
1) the function was converting from 100ths of nanoseconds to seconds
rather than 100s of nanoseconds to seconds by dividing by
(nsPerSecond * 100) rather than (nsPerSecond / 100)
2) the function should've been returning milliseconds, not seconds
