Not quite. They are running at 1, 2, 3, 4 minutes after the hour. Cron=20
timing works off five columns. Left to right, those columns are
Minute - Hour - Day - Month - Weekday
The value specifies in each columna allows for timing. Googling reveals

for more information.
So hourly runs exactly when it says it will, hourly. Specifically, at *:=
01 on=20
the clock. In your list Daily check the minutes (:02) and the hour (4:) =
and=20
when they match (4:02) it runs, and since 04:02 only happens once a day, =
it=20
works. =20

noon, and your clock is 10 minutes fast, I would assume it is a cron job.=
