如何使用本工具

  1. 1

    Pick a date and time in the datetime-local field; it defaults to right now and is read as your computer's local time.

  2. 2

    Choose a destination zone from the 'To' dropdown (UTC plus 12 common city zones across the Americas, Europe, Asia and Australia).

  3. 3

    Read the converted full date and time shown in the highlighted box below, formatted in US English.

  4. 4

    Adjust the date to a different day if you want to check how daylight saving shifts the result.

什麼是時區轉換工具?

時區運算是出了名的容易出錯:夏令時間規則因國家而異,且每隔幾年就會變動。本轉換工具使用瀏覽器內建的Intl.DateTimeFormat,它遵循目前的IANA時區資料庫。若需在伺服器端處理時區,請使用Luxon或date-fns-tz這類函式庫。

常見使用場景

  • Check what time your 3pm local call lands at for a colleague in Tokyo, Berlin, or Sydney.

  • Confirm the UTC equivalent of a local deadline before filing it in a ticket or changelog.

  • See whether a date you picked falls inside daylight saving by comparing two nearby dates.

  • Translate a webinar start time from your local clock into a US Eastern or Pacific figure for an announcement.

  • Sanity-check a cron or batch-job time you reason about in local terms against UTC.

  • Plan a flight or call window by reading your departure-local time as it appears in Asia/Kolkata or America/Sao_Paulo.

常見問題

它能處理夏令時間嗎?
可以:Intl.DateTimeFormat會根據你所選的日期自動套用夏令時間規則。
為什麼會議預設使用PST或UTC?
PST/PDT涵蓋矽谷地區;UTC則與時區無關,屬於中立選擇。請務必在邀請中註明時區。
