negative seconds in Delta evan if days is non-negative

[Hanaasagi]

code example:

    const now = datetime.Datetime.fromSeconds(1686183930);
    const future = datetime.Datetime.fromSeconds(1686268800);
    const delta = future.sub(now);

    std.debug.print("future => {s}\n", .{try future.formatHttp(testing.allocator)});
    std.debug.print("now    => {s}\n", .{try now.formatHttp(testing.allocator)});
    std.debug.print("delta  => {any}\n", .{delta});

Output:

future => Fri, 9 Jun 2023 00:00:00 UTC
now    => Thu, 8 Jun 2023 00:25:30 UTC
delta  => datetime.Datetime.Delta{ .years = 0, .days = 1, .seconds = -1530, .nanoseconds = 0, .relative_to = null }

In the output, I noticed that the delta has a days value of 1 and a negative seconds value of -1530. To make it more convenient for comparing delta.days > 1, Would it be possible to changing the delta to have days = 0 and seconds = 84870?

Makes sense, please review d21cc01 and let me know if that works. Thanks!
