[Avodah] Fwd: b'Ito u'b'Zmano

[Micha Berger]

I mentioned Friday night, at RZL's grandson's Shalom Zakhar, a notion from
R' Yaakov Kamencski about zeman and eis. One of the attendees asked:
: Do you have a source reference where I can see what Rav Yaakov's
: explication was, that prompted his adjusting  the Nusach?

Looking through Avodah's archive, since I remember discussing this here
before, I found that in the past I thought it was from R' Aharon. To
quote:

> R' Aharon Kotler zt"l commented to a student on the occasion of the
> birth of the student's son about the phrase "The beris should be
> be'ito ubizmano", using both "eis" and "zeman" to denote its proper
> time. Similarly the famous words of Koheles, "Lakol zeman va'eis...
> everything has its zeman and its eis..." Rav Aharon explained the
> difference. If the baby is healthy, then the beris is at the
> pre-decided time, on the eight day. If not, then it will be at the
> right time for that individual baby. Ideally the beris would be at
> both.

> An eis is a time that comes according to a prescheduled appointment,
> ready or not. It is a point in a shanah, in cyclic time that runs its
> celestial heartbeat regardless of human action. A zeman is a landmark in
> the course of progression. And so, one is "kovei'ah itim baTorah", one
> sets aside times for Torah. In Ma'ariv, we describe Hashem as "Meshaneh
> itim uMachalif es hazemanim -- the One Who changes the itim and switches
> the zemanim." Note that for "itim", the change is described as a shinui,
> reflecting the word shanah.

So, does anyone know who did say it, where it really does come from?
