Tools as reported by the server

• time_now
  The current time: Unix epoch in seconds and milliseconds, ISO 8601, and the local wall-clock time in a given IANA time zone with its current UTC offset and DST status. Use this before any relative date reasoning.
• convert_timestamp
  Convert a Unix timestamp (seconds or milliseconds; auto-detected unless unit is given) to a human-readable date in a time zone, with ISO 8601, RFC 2822, UTC offset, DST flag, weekday, and a relative phrase like "3 days ago".
• parse_datetime
  Parse a date/time string (ISO 8601, RFC 2822, HTTP date, SQL "YYYY-MM-DD HH:mm:ss", or a Unix timestamp) into a Unix timestamp and a normalized description. Strings without an offset are interpreted in the given time zone.
• convert_timezone
  Convert a wall-clock date/time from one IANA time zone to another, correctly across daylight-saving transitions. Returns both sides with offsets, the hour difference at that instant, and whether either zone is on DST.
• date_duration
  The exact duration between two dates or date-times: calendar years/months/days, plus total days, hours, minutes and seconds, and the number of weekdays (Mon-Fri). Handles leap years and DST via the IANA database.
• epoch_math
  Add to or subtract from a Unix timestamp in calendar-aware units (years, months, weeks, days, hours, minutes, seconds) in a time zone, e.g. "now + 30 days" or "1748736543 - 3 months". Returns the resulting timestamp in every format.
• cron_next_runs
  Explain a 5- or 6-field cron expression in plain English and list its next run times in a time zone (as ISO 8601 and Unix timestamps). Use to answer "when does this cron job run next?" or to validate an expression.
• days_until
  Countdown to a holiday or to a date: days, hours and minutes remaining, and the next occurrence date. Pass an event slug (e.g. "christmas", "thanksgiving", "easter", "super-bowl") or a date (YYYY-MM-DD). Call with no arguments to list the known events.
