getUTCtime() increases irregularly

[david]

Hello,

I was just playing with a slow down class, when I noticed
getUTCtime() from std.date works a bit unexpected:

import std.stdio;
import std.date : getUTCtime;

int main(char[][] args)
{
	for (int i=0;i<500;i++)
		writefln(getUTCtime());
	return 0;
}

results in (shortened version, for obvious reasons):

So, it increases as well in large increments
and also in irregular ones, namely
15 and 16 milliseconds.

Since I found nothing in the phobos docs,
how can I access the current time at a more
precise level?
