由 和自甴很熟 提交于 2021-02-20 03:31:26
问题 in my app i have set a periodic job that is set to run every 30 minutes. The first job run occurs right when I do schedule that periodic job, which is not wanted in my case. What I want is to skip the first run so that it will run for the first time after 30+ minutes.
