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.
