time

Give a local model a sense of now. LLMs are reliably wrong about today's date, relative dates ("next Tuesday", "in 3 days"), and timezone math — this plugin removes that whole class of mistake.

Part of lmstudio-suite.

Two halves

• Date/time injection (prompt preprocessor) — prepends one line to each message, e.g. Current date and time: Thursday, June 18, 2026, 2:30:05 PM CST (timezone America/Mexico_City; ISO-8601 2026-06-18T14:30:05-06:00). so the model always knows the current moment without a tool call.
• Date/time tools (tools provider) — for exact computation when the model needs it.

Tools

Tool	What it does
now	Current date/time in any IANA zone. Formats: iso, human, date, time, unix.
time_until	How far a target is from now as a phrase — in 3 days, 4 hours / 2 hours ago.
add_duration	Add/subtract a duration (seconds…years); months/years are calendar-aware and clamp end-of-month.
diff_dates	Difference between two datetimes — a human phrase (auto) or the exact number in a fixed unit.
convert_timezone	Convert a datetime between zones; pass from to anchor an offset-less wall time.

Configuration

• Default timezone — IANA name (e.g. America/Mexico_City) used by the injection and the tools when none is passed. Leave blank to use this machine's timezone.
• Inject current date/time — toggle the always-on date line (on by default).
• Expose date/time tools — toggle the five tools (on by default).

Notes

• All timezone handling uses the built-in Intl API: IANA zones, DST-aware, no dependency.
• Pass datetimes as ISO-8601. Include a Z/offset for an unambiguous instant — an offset-less datetime is read as local time per the ECMAScript spec (except in convert_timezone, where from overrides this).
• The injection never blocks a message: a bad timezone config passes the message through unchanged.
