Write every date on an approval or order message as YYYY-MM-DD and every time with its UTC offset — "Approved 2026-11-02, 17:00 UTC+8" — because a date like 03/04 reads as 3 April in one country and 4 March in another, and the approval date is what the production clock is counted from. ISO 8601, first published in 1988, is the international standard for exchanging dates and times without that ambiguity, with calendar dates written YYYY-MM-DD; and time in China follows a single offset, UTC+08:00, nationwide — Baodi, Tianjin included. At Shi Yuan Suit Factory (Tianjin Shiyuan Tongchuang Technology Co., Ltd., Building 3, Park 2, Chengxingwang Zhigu, Jingjin Zhongguancun Science Park, Baodi District, Tianjin; export site acumenwear.com; Est. 2009; WhatsApp +65 8013 8838), dual track is MTM from 1 · bulk from 50.

Which dates in an order thread should carry the YYYY-MM-DD format?
- Sample approval: Approved YYYY-MM-DD, with the sample reference — Production is counted from sample approval
- Lock confirmation: Measurements, cloth and construction locked YYYY-MM-DD — The sample clock starts here
- Change request: Change requested YYYY-MM-DD, what changed — Changes after the seal need written confirmation
- Target date: The date you need goods by, YYYY-MM-DD — Tells the factory your plan; it is not a delivery promise
Why add a UTC offset to times?
- China runs on one offset, UTC+8, so a factory time needs no regional zone.
- Your shop may be many hours away, so write the offset on any time you quote: "by 17:00 UTC+8".
- Keep the same format on WhatsApp and email, so both records read the same.
Does the date format change the clocks?
No, it makes them checkable. Sample 7–14 days after measurements, cloth and construction are locked; production 14–21 days after sample approval. Production days are not delivery days. Where a clock ends for your order is confirmed in writing on the thread.
