Create a task that should run based certain frequency If client and server are at different time zone












0














I'm working on my college project which allow user to create task that should run on different frequency and we are using spring cron Trigger for this. have few doubt and need clarification on the same.




  1. Assume currentDate: 2018-11-13T13:00:00.000+05.30 (IST timezone) and we want to run task after 10 min. In case of run every n days(2, 3, 4 ...) interval, cron always generating next run date from currentDate + 1. but for run every day(where n=1) It start from currentDate. Not sure Whether it is expected behavior or not.

  2. Weekly frequency: Can run on multiple days of the week and currently we implemented for run-every week, not sure how to generate cron for bi-weekly and run n-week interval.

  3. Monthly frequency: Allow user to select which week(first, second, third, forth and last) and which day on that week. Eg: if user select first week and select day as WED then task should run on every month first WED, while generating cron i'm pre-defining date range i.e first week(1-7), second week(8-15) because in most of the cases first WED always falls between 1-7 but found many exception cases.

  4. Which time zone(client, server or UTC) is preferable for generating cron expression for minute and hour field. actually I used server time for this, but problem is sometime weekly and monthly frequency starts from next date though It didn't cross current day time. and some time 1hr getting added for next run date(not sure because of day light saving, server at PST timezone). this scenario is working fine if both client and server are at same time zone.
