what it does

localizer scans pages for times with timezone labels and quietly rewrites them to your local time. the page looks like it was always written for you.

built this because i was on claude status page, "11:49 UTC." what the fuck is a UTC. also what the hell did those shows mean by 8/7 central who was this designed for.

install

npx localizer-ext                # npm

or

bunx localizer-ext               # bun

or

curl -fsSL https://raw.githubusercontent.com/zaydiscold/localizer/master/install.sh | bash

or

wget -qO- https://raw.githubusercontent.com/zaydiscold/localizer/master/install.sh | bash

or

git clone https://github.com/zaydiscold/localizer

then in chrome:

1. go to chrome://extensions
2. turn on developer mode (top right)
3. click load unpacked
4. select the folder

usage

it just runs. every page, automatically.

handles 11:49 UTC, 2:30 PM EST, 2026-03-02 14:00 GMT. catches 30+ timezone abbreviations. doesn't ask questions.

toggle it on/off from the extension icon in the toolbar. that's the whole settings page.

note: watches dynamic page updates now, so status dashboards that load late content should still convert.

_{supported: UTC, GMT, EST, EDT, CST, CDT, MST, MDT, PST, PDT, AKST, AKDT, HST, AST, ADT, NST, NDT, CET, CEST, EET, EEST, WET, WEST, IST, JST, KST, AEST, AEDT, ACST, ACDT, AWST, NZST, NZDT. yes i looked up what all of these mean. none of them have cool magnetic anomalies like the Central African Republic.}

updates

no auto-update yet (unpacked extension). when you pull new changes:

1. go to chrome://extensions
2. click reload on localizer
3. hard refresh tabs where you want it running (cmd+shift+r)
