DolphinScheduler allows flexible configuration of time parameters for task scheduling needs.Time parameters can be defined as global parameters and used throughout workflows or tasks.Time window parameters like ${startTime} and ${endTime} are useful for data processing tasks.Cron expressions enable precise task scheduling, e.g., running tasks daily or weekly.Complement tasks in DolphinScheduler involve specifying time ranges for re-execution.Time formatting functions allow for date addition and subtraction in time parameters.Built-in time parameters like ${system.biz.date} are available for immediate use in scripts.Time-dependent task chains can be configured using time parameters across workflows.Functions like add_months() allow for time manipulation, e.g., adding/subtracting months or days.Overall, time parameters in DolphinScheduler support various scheduling and data processing needs efficiently.
