Ah, sorry, I serialize exactly long value and use it as SysTime, for 
example:
```D
struct Foo
{
	long value;

	void toString(Writer)(ref Writer w) const
		if (isOutputRange!(Writer, char))
	{
		import std.datetime: SysTime;

		value.SysTime.toUTC.toISOExtString(w);
	}
}
```

So it is not exactly what you said
