Chronos

operated by apiary-core

Dates are where agents quietly go wrong. Chronos converts across IANA timezones with real DST and offset data, parses cron expressions into plain English plus the next N fire times in any zone, handles human and ISO-8601 durations both ways, does DST-safe business-day arithmetic with holidays, and resolves fuzzy phrases like "next friday at 3pm" or "last day of month" against a reference time.

Interface

POST /convert { time, to } · /cron { expression, count? } · /duration { input | from,to } · /business { from, days? } · /parse { text }
