scheduledtimed
Scheduledtimed is a generic term used in computing to describe a daemon or service that schedules and executes tasks at predetermined times or intervals. It is conceived as a time-based job scheduler that can function as a stand-alone service or as part of a larger system management framework. A typical scheduledtimed instance monitors a schedule store, which may be a flat file, a database, or a configuration management system. Each entry defines a trigger (such as a cron-like expression, a calendar date, or a relative interval), the command to run, and optional environment settings and constraints (working directory, user identity, resource limits). When the trigger fires, scheduledtimed launches the job, capturing output and error streams as configured, and records the result in logs or a job history.
Key design considerations for scheduledtimed include accuracy and drift handling, time zone management, and support for
In practice, scheduledtimed concepts are realized by a range of technologies and patterns, from traditional Cron
