2026-11-09meridian_nowchangeddescription
before
Use when you need to know what time or date it is right now somewhere. You have no clock of your own, so never guess the current time. Returns the real current time, date, UTC offset, abbreviation and daylight saving status for each place. Places can be cities ("Tokyo"), IANA zones ("Europe/Paris"), abbreviations ("PST") or "UTC+5:30".

Use when the user asks what time or date it is right now somewhere. Reads the server clock and returns the current time, date, UTC offset, abbreviation and daylight saving status for each place. Places can be cities ("Tokyo"), IANA zones ("Europe/Paris"), abbreviations ("PST") or "UTC+5:30".
2026-11-03meridian_zone_infochangeddescription
before
Use to answer "what is the UTC offset of X", "does X observe daylight saving" and "when do the clocks change". Returns the current offset and abbreviation, whether the place observes DST, every clock change in the year with exact local before and after times, and the next change. Abbreviations like IST or CST are ambiguous, so the answer says which zone was used.

2026-11-03meridian_meeting_slotschangeddescription
before
Use to schedule a call across several places. Scans the day in 15-minute steps and ranks start times so the most people are inside working hours and nobody is at night, using each place's real offset and DST for that date. Returns up to 5 slots with each person's local start and end, and says plainly when no time works for everyone. Defaults: working hours 9 to 17, 60 minutes, date today in the first place.

2026-11-03meridian_convert_timechangeddescription
before
Use to convert a specific wall-clock time from one place to others, for any date. It uses the real tz database, so daylight saving is right for that exact date (the US and Europe switch on different weeks), and it warns when the time does not exist (spring forward) or happens twice (fall back). Time accepts "15:00", "3:30pm", "noon", "now" or an ISO local time like 2026-11-05T15:00 (no Z). Date defaults to today in the source zone. Returns {input, utc, source:{...}, converted:[{place, zone, local, time_12h, date, utc_offset, abbreviation, day_note, hours_ahead_of_source}], warning?, summary, open_url}.
