印度不調整夏令時間，離岸團隊的重疊工作時間會如何變化
India doesn't change its clocks. Here's what that does to your offshore team's overlap
美國於 11 月 1 日將時鐘撥慢一小時，印度不調整時鐘，因此美印團隊週一的重疊工作時間減少一小時。以海得拉巴團隊配合客戶當地 09:00 至 18:00 的班次為例，紐約冬季每日重疊 4 小時，夏季則為 5 小時。文章建議把例行會議安排在重疊時段內，並以書面交接、每日簡報及清晰的非同步訊息減少等待。
US clocks go back an hour on Sunday 1 November. India's never move, so every team working between the two loses an hour of shared time on Monday.
Here's the overlap we plan around, for a client working 09:00 to 18:00 local time and a team in Hyderabad on a matched shift.
| Client city | Team hours (IST) | Daily overlap |
|---|---|---|
| New York | 14:30 to 23:30 | 4 hours in US winter, 5 in summer |
| London | 11:00 to 20:00 | 5½ hours in UK winter, 6½ in summer |
| Dubai | 10:00 to 19:00 | About 8½ hours all year |
| Sydney | 07:00 to 16:00 | 5½ hours in the southern summer, 6½ in winter |
New York is the tightest window. In US winter, 09:00 Eastern is 19:30 in Hyderabad, so shared time runs from 19:30 to 23:30 IST.
This week's checklist
- Move recurring meetings so they still land inside the overlap.
- Check any handoff that relies on someone seeing it before they log off.
- Decide whether the shift moves with your clocks or stays put, and confirm it in writing.
Protect the overlap
Don't spend it on status. Post a written standup at the start of each person's day, with four lines: yesterday, today, blockers and FYI. The required blockers line matters most, because it makes raising a problem routine.
Use the shared hours for decisions, pairing and design reviews. Before logging off, each side writes down what finished, the exact state of what's in progress, open questions with a named owner, and what the other side should pick up first.
Write messages that don't need a reply
- Incomplete: "The users API is broken."
- Complete: "GET /api/users returns 500 with an expired token. Expected 401. I suspect the error handler. Draft fix in PR 412. Needed before Thursday's release."
Each clarifying question can cost half a day, so that second version pays for itself.
