You also know that you have such a requirement, and obviously also know
what you could do to fix it.

I see this as a non-issue. Even if we *try* to sync with the second
transition (which is likely rather hard to do) then we won't have the
required precision for a bunch of applications, so it's futile to try it
anyway.

Besides, if we don't do it at all the time just keeps running where it
was before suspend...
