Answer 1

In Jenkins, use this in "Build periodically" to run for every 90 mins H/30 H/2 * * *

Answer 2

You may have to specify two cron jobs for it in the scheduler like this in the same jenkins job - very similar to what one would do for a normal cron in Linux

45 1,4,7,10,13,16,19,22 * * * /path/to/script
