טו לדברי רבי יהודה אדם טועה חצי שעה מעשה כי הוה בפלגא דארבע הוה והאי דקאמר שלש בסוף שלש וקטעי פלגא דשעתא לקמיה והאי דקאמר חמש בתחלת חמש וקטעי פלגא דשעתא לאחוריה
15 [Thus:] on R'Meir's ruling a man does not err at all: the event [to which they testify] happened at the end of the second and the beginning of the third [hour], and when one says, during the second, [he means] at the end of the second [hour], and when the other says, during the third hour, [he means] at the beginning of the third hour.<span class="x" onmousemove="('comment',' Thus there is no contradiction at all. But if it is shown that there is a contradiction, even in half an hour, one is assumed to be false and their evidence is null.');"><sup>11</sup></span> On R'Judah's ruling a man may err in half an hour: the event happened in the middle of the fourth hour, and he who says in the third hour[meant] at the end of the third hour, and he errs in [being] half an hour before; while he who testified, in the fifth hour, [meant] at the beginning of the fifth hour, and he errs half an hour behind.
