Timezone Hover Converter 作成者: Amadeus

Stop doing timezone math in your head.

Timezone Hover Converter watches for times written with a timezone next to
them — things like "9 AM PT," "14:00 UTC," or "6:45 PM BST" — anywhere on a
webpage. Hover your mouse over one, and a small bubble pops up showing that
time converted to your own local timezone.

How it works
- Set your local timezone once in the extension's options.
- Browse normally — Slack threads, emails, event pages, GitHub issues,
wherever times with timezones show up.
- Hover over a highlighted time to see the converted version. No clicking,
no copy-pasting into a separate converter.

Supported timezones
Recognizes common abbreviations across North America (PT/PST/PDT, MT, CT,
ET, AT, HST, etc.), UTC/GMT, Europe (BST, CET, EET, MSK), Asia (IST, JST,
KST, HKT, SGT, GST, ICT, PKT), and Australia/NZ (AEST, ACST, AWST, NZST)
— all with daylight saving time handled automatically based on today's
date.
