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

=09Most cron jobs are set to run early in teh hour, so if it was just bef=

noon, and your clock is 10 minutes fast, I would assume it is a cron job.=
 =20
(11:55 + ~10).
