I'm attempting to print a human-readable version of a timestamp. The

It's kind of convoluted because there is no epoch, but you can make one:

import std.datetime;
import std.stdio;

void main(string[] args)
{
    // can't make this enum because of time zone...
    auto epoch = SysTime(unixTimeToStdTime(0), UTC());
    writeln(epoch + 1_421_865_781_342.msecs);
}

output:
2015-Jan-21 18:43:01.342Z

Note the reason your code didn't work is because SysTime uses 1/1/1 as 
the epoch.
