I'll change the library to follow the settings of the user's env var
and assuming they've set it correctly, all will work well.  Since
libxo uses vsnprintf under the covers, all this should work fine.

    (void)wcsftime(buf, sizeof(buf), fmt, &tp);
    ...
    xo_emit("{:login-time/%ls}", buf);

Or something like that......

Thanks,
