There is a process which needs to run 4 times a day: 5am, 9.30am, 2pm and 8.30pm respectively. I found a CRON Expression : 0 0 5,9,14,20 ? * * which will run at the 0th minute i.e. at 5 am,9 am,2 & 8 pm, but not with a combination of running at 0th and 30th minute as per my requirement.
Does anyone have an idea for creating a CRON expression to define time for running at 0th and 30th minute as well?
