Scheduling and Time-Based Tasks for Developers

Getting a cron expression right, and making sense of the timestamps it produces.

Building and verifying the cron expression comes first since it's the actual scheduling decision -- when a task should run. The timestamp converter comes second because once a scheduled task is running, the next real need is usually making sense of the Unix timestamps that show up in logs from that task, which is a genuinely separate problem from writing the schedule itself.

Each step opens as its own tool -- download from one, upload into the next, same as any free tool on the site.
