PRECISION WITH PROOF
Open Time Appliance
Clock Quorum unites IEEE 1588 grandmasters into a self-verifying network: indisputable, secure, fault-tolerant time. Because sync without consensus is guesswork.

Why buy from Timebeat
Built in Britain
Designed and built by the Timebeat engineering team in the UK.
Proven at scale
The same hardware and software run by NASA, Netflix, Nokia, Disney, Garmin and Panasonic.
3 month warranty
All hardware carries a 3 month manufacturer warranty covering manufacturing defects.

Questions go to the engineers who build the products, before and after you buy.
QUESTIONS
Before you buy
Do you ship to my country?
We ship worldwide from the United Kingdom. Orders are typically dispatched within 48 hours via Royal Mail or DHL, and other couriers may be used for some destinations. Shipping options and costs for your address are shown at checkout. International customs charges and import duties are the responsibility of the buyer. If you do not see your region at checkout, get in touch and we will arrange it. UK orders over £500 ship free.
When will I receive my order?
Most products are delivered within 1 to 2 weeks. Specialty appliances and pre-order units can take longer. Express shipping is available on certain units, so if you need a shipping method you do not see online, contact us.
Is the product I need in stock?
Each product page shows availability. Items marked out of stock cannot be ordered right now, and some items are built to order with a 1 to 2 week lead time or offered as pre-order. If in doubt, ask us before ordering.
Can I get a quote or volume pricing?
Yes. For project pricing, volume orders or a formal quotation, contact sales@timebeat.app or use the contact page and an engineer will come back to you.
Which product do I need?
A rack environment usually wants the Open Time Server or Open Time Appliance. A single machine or lab is often best served by the Open Timecard Mini. If you are unsure, talk to an engineer and describe your network. We will point you at the smallest thing that does the job.
What warranty comes with the hardware?
All hardware carries a 3 month manufacturer warranty covering manufacturing defects. Damage caused in use or installation is not covered.
What if something arrives faulty or damaged?
We do not offer a general returns window. If an item arrives damaged, faulty or not as ordered, contact sales@timebeat.app straight away and we will repair, replace or refund it under the 3 month manufacturer warranty. Your statutory rights are not affected.
Where do I go for support?
Support and documentation live at support.timebeat.app, and technical questions are answered directly by our engineering team.
