Time

Convert timestamps and explain cron schedules.

• Unix Timestamp — Convert a whole number of Unix seconds or milliseconds into UTC and local time, and read an ISO-8601 instant back to both units. Words and time-zone names are not accepted as input.
• Cron Helper — Explain a five-field cron expression and list the next UTC run times. Seconds, years, and Quartz-only syntax are not accepted, and nothing is installed.
