ClockinSync - Smart Timezone Extension
World Clock & Time Zone Converter For Worldwide Remote Teams
Most world clock tools just show time. ClockinSync goes further: automatic DST warnings before shifts catch you off guard, Public Holiday alerts for every city you track, Working-Hours overlap to see team availability instantly, and a /time shortcode that converts time inline without leaving your chat or doc. 23,000+ cities, per-client clock profiles, and both popup and side-panel modes.
Hey Product Hunt 👋 I'm Indrit, and I built ClockinSync at 2 AM.
I was trying to figure out if it was a reasonable hour to message a client in Singapore, while a Toronto call was coming up in the morning, and someone from Berlin had just pinged me asking when we could sync.
Three time zones. One brain. Zero good tools.
Every converter I tried felt clinical, type a time, get a number, do the mental math yourself. None of them could answer what I was actually asking: is my colleague in Dubai even at her desk right now? Is 4 PM in my city a fair ask for someone in LA?
So I built something that could.
ClockinSync started as a personal tool, not a startup. Just something I needed, built the way I needed it, working hours overlap at a glance, DST warnings before they catch you off guard, holiday alerts so you stop booking meetings nobody attends.
Then I realized I wasn't alone.
No VC behind this. No growth team. Just a genuine problem and a strong belief that the best tools are built by the people who need them most.
If it saves you even one awkward late-night message, it's doing exactly what it was built to do.
Check out ClockinSync extension and use it for free no strings attached. If you like it and want to upgrade here is a coupon that you can use at checkout for 50% OFF : PH50OFF valid for upgrades until 31 May 2026
