linux - How precise is a cron daemon?

Is the cron job scheduler really precise?



I mean, I need a script to run every night the latest possible, BUT before 00:00 of the next day.




I'd ideally run a cron job at 23.59 (or 11:59 pm), but will the system be really precise? Since a second does matter, should I set the cron job to 23:58 to leave it some time?
