एतेतौ रॱथोः ONPANINI 53004

(Replace /idam-, when it means time,) with eta एत before r र् and with it इत् before th थ् (of a /prAgdizIya).

This debars the /iz from < idama::iz.

/idam- + /rhil from idamorhil 12>
→ eta एत eta + /rhil by this rule
→ **etarhi एतर्हि "at this time"

/idam- + /thamu from idamasthamuH 20>
→ it इत् + /thamu by idamorhil 12>
→ **ittham इत्थम् "in this way"

Why do we say "when it means time"?

When /idam- means a place, we get **iha इह iha "here", by idamohaH 7>.
