Gemini

Where to operate

Ordinary Gemini web text chat

Getting started

  1. Use authorized de-identified short text, choose your own parameters and keep the original.
  2. Paste the prompt and fixture into ordinary Gemini web text chat without connecting services.

Setup and plan requirements

Prefer an adult personal account. Official web lists include Hong Kong, Macau, Taiwan and Traditional Chinese. Local connections were not tested.

Prompt portability limits

Standard limits exist without a paid plan. Usage caps vary; local paid prices are unverified. No specific model or prompt count is guaranteed.

Usage limitations

Mobile/API/CLI are outside this check. No accounts are read, devices controlled, messages sent or purchases made. Do not supply secrets; activity-off chats may remain for 72 hours and receive safety processing.

適用情境 / When to use

Convert deadlines with explicit UTC offsets and flag missing timezone details. Fictional fixture: 2026-11-13 23:30 UTC−5 to UTC+8. A second item only says Friday evening.

步驟 / Steps

  1. Use authorized de-identified short text, choose your own parameters and keep the original.
  2. Paste the prompt and fixture into ordinary Gemini web text chat without connecting services.
  3. Human check: UTC is Nov 14 04:30 and target time Nov 14 12:30. The second item lacks a date, zone and exact time; do not invent them.
  4. Check against the human answer and source. Preserve errors; never present an expected answer as observed output.

提示詞 / Prompt

Convert [source date/time and offset for that date] to [target offset for that date]. Show original, intermediate UTC and target date/time. Preserve the wording. Flag missing offsets or daylight-saving evidence; do not guess from a city. Do not create calendar events or commit to deadlines.

Fictional fixture: 2026-11-13 23:30 UTC−5 to UTC+8. A second item only says Friday evening.
