🟢explore_cron(expression, timezone, reference, count)
Use this when you want to explain a five-field cron expression, find its next runs in an IANA timezone, or inspect daylight-saving transitions. Supports numeric *, lists, ascending ranges, and steps. Requires an explicit timestamp reference. Searches up to 1,830 days and returns up to 20 runs strictly after it. Does not execute jobs or support names, macros, seconds, years, ?, L, W, or #.
