About Timezone Tooltip- Highlight Text to convert timestamps (FREE)
Timezone Tooltip is your “wait…what time is that for me?” superpower. 🕒✨
Just highlight time text anywhere on the web and instantly see it converted into your chosen time zones—no new tabs, no mental math, no calendar gymnastics.
Q: What can it convert?
A: The stuff you actually see in the wild: “3pm PT”, “14:30 UTC”, “10:00 +0530”, “7:15pm”, and even sneaky relative words like “today / tomorrow / yesterday”.
Q: What if a site shows times with NO timezone at all?
A: That’s where the magic settings come in. You can set a default timezone per site so the extension knows what the page “really means”.
★ URL Rules (aka “make every site behave”)
➜ Pick a domain and say: “On this site, treat times as [my selected timezone].”
➜ Or toggle Strict URL mode and say: “Only on THIS exact page URL, treat times as [timezone]. Everywhere else? fall back to my normal default (local timezone).”
Perfect for dashboards, docs, ticketing tools, and internal pages that assume a timezone but never bother to tell you.
Q: Can I make the tooltip feel more human?
A: Yep. Rename timezones to whatever makes sense in your brain. Call them “SF 🏄”, “NYC 🍕”, “London ☕”, “India 🇮🇳”… and the tooltip will show your custom names.
Q: Can I customize what shows up?
A: Absolutely. Choose your target timezones, reorder them, and keep the list lightweight so it’s fast and snappy.
