I've managed to make it work using 'alias this' and wrapper

It's not an elegant solution, there could be a better way to do
this.
Yea, a wrapper struct with custom `toString` seems the most
obvious way forward. No need to bother with `alias this`,
though, since one only needs the wrapper struct at the point
where one wants to format the datetime info. A wrapper struct
like this:
struct ISOExtSysTime
{
private SysTime systime;
public void toString (Output) (ref Output output)
if (isOutputRange!(Output, char))
{
this.systime.toISOExtString(output);
}
}
allows easy usage along the lines of:
writefln!"%s"(ISOExtSysTime(sys_time));
... and one could easily write a small factory function to
shorten the code if needed.
