SysTime already supports fractional seconds. This already compiles and runs
just fine:

---
void main()
{
    import std.datetime;

    auto dt =
cast(DateTime)SysTime.fromISOExtString("2024-08-15T08:13:23.000");

    assert(dt.year == 2024);
    assert(dt.month == 8);
    assert(dt.day == 15);
    assert(dt.hour == 8);
    assert(dt.minute == 13);
    assert(dt.second == 23);
}
