Run some taks hourly but start in different time

Hi, thank you for helping me setup this plugin, it works. I need another advise.
So here is my problem,
For example I have 3 task to run every one hour (hourly)
my_cronjob_1_action
my_cronjob_2_action
my_cronjob_3_action
Is there any tips to prevent those jobs run in the same time together?
I need something like this
my_cronjob_1_action run 00:10 so the next run is 01:10
my_cronjob_2_action run 00:30 so the next run is 01:30
my_cronjob_3_action run 00:45 so the next run is 01:45

because if all of them run in the same time at 00:00 and the next run is 01:00 it will kill my server.

Thank you before.
