Time Zone Clocks/Displays
Founded in 2006, OnlineClock.net is the world's original Online Alarm Clock & your Go-To source for Free Timers, Stopwatches, Countdowns, Counters, Clocks and other web-based Time Tools! Digital online clock with seconds. Full screen with big digits. Format options are 12h and 24h.
BRG manufactures time zone clocks to fit your needs. BRG clocks are factory synchronized with the U. S. Atomic Clock and will remain accurate for the life of the display. We offer four types of time zone clocks - Analog, Alpha, Fixed Zone and Programmable Zone. Click on the photos below to get more details. | |

BRG digital time zone clocks are capable of displaying all known world time zone rules, including rule based daylight saving time, 30 minute time zones, and more. If a country changes daylight saving time rules, the change can easily be implemented in the field without the need for factory programming or firmware updates. Digital time zone displays will provide any combination of time zone and display formats, including UTC (Zulu) Time, Any World Time Zone, Half-hour time zones, Enable or Disable Daylight Saving Time, and 12 or 24 hour display formats, with or without leading zeros. An IR remote control is included with all digital time zone displays. RF remotes are optional. Accurate for Life – no manual adjustments are required for the life of the display. No GPS, sync wiring or network wiring. High Reliability. Factory synchronized with the U.S. Atomic Clock. Programming and time is maintained during power outages. For those that require external time sources, we offer GPS, NTP (Network), IRIG-B, and SMPTE time receivers to synchronize the time zone display with the U.S. Atomic Clock or other time server. Specify custom lettering from left to right when ordering. Digital bar segments are available in Red, Green and Blue LEDs. The digital zone labels are available in Red, Green and Yellow. The standard high brightness bar segment displays are ideal for indoor applications, but they cannot be seen in direct sunlight, or highly reflected sunlight. For indoor use, the intensity can be reduced for normal viewing, or increased for greater viewing distance. BRG welcomes requests for customized time zone displays to meet your individual needs. Contact one of our Salesmen today at 800-295-0220.There is an auto brightness option that allows the display intensity to automatically adjust LED brightness to ambient light. BRG also offers a Wireless 2.4 GHz analog Time Zone Display for retro look. You can feature up to 18 different time zones, 15 and 30 minute offsets, including DST rules. Analog clocks are available in 12' and 15' diameters and Brushed Aluminum or Black Plastic Finishes. Call 866-252-2704 or 316-530-8854 |
USER CHANGEABLECOLOR is standard on all BRG LED digital clocks.
BRG Time Zone Clocks are accurate for life without the need for manual or external time updates. A GUI touch screen IR remote control is available to ease configuration.

WWV Simulator
UTC To Z
This site attempts to simulate the audio portion of stations WWV and WWVH. It should sound much like what you’d hear if you tuned in a shortwave radio to one of these stations. Each station has its own style of tones and voice time announcements. Station identification is every half hour.
This is only an simulation, using your computer’s time and samples of the audio. It is not a rebroadcast of the real stations.
What is WWV?
WWV is a radio station run by the National Institute of Standards and Technology (NIST) that broadcasts precise time and frequency from Fort Collins, CO. A companion station, WWVH, provides a similar service from Kekaha, HI. The time sources are highly accurate atomic clocks. These broadcasts contain an audible portion (which this site emulates), and a digital time code that can be received by clocks and watches for automatically maintaining precise time.
WWV has operated continuously since 1919, but in 2019 its future was in doubt due to proposed budget cuts that could have shuttered the stations. Fortunately the final NIST budget preserved the funding.
Why make this site?
I have fond memories of WWV being one of the first stations I picked up when I got my ham radio license many years ago. It was one of the few stations that could nearly always be picked up on some frequency, even during poor propagation. When conditions were good, sometimes I could also hear WWVH (Hawaii → Chicago is a bit of haul). Besides just tuning it in, I actually liked having it on while doing my homework! The steady pulses, curious patterns of tones, and old-timey timbre of the occasional voice announcements made for nice background noise.
WWV has never (to my knowledge) been streamed over the internet. There are many sample recordings available, but nothing that just runs and reflects the current time. Creating a simulated WWV website has been on my “someday” project list for a long time, but the threat of WWV/H being shut down provided serious motivation to make it a reality. Even if NIST does power down the amplifiers, this site can still provide a reasonable representation of what those iconic stations sounded like.
How Accurate is It?
Time-wise, this site is exactly as (in)accurate as your computer or phone clock currently is. As far as how well it matches the real WWV/H transmissions, my goal has been to mimic the audio portion as closely as reasonably possible. The stations have distinct patterns of pulses, tones, and voice announcements which have been implemented. The simulation includes all of the elements except for real-time voice announcements, such as space weather reports, and some really esoteric things like special adjustments for leap seconds. If you find an error, let me know!
Utc Time Clock For Desktop
Note: if you’re listening with bluetooth headphones, the pulses and clock might be slightly out of sync. Furthermore, if the browser doesn't have focus or the tab isn’t active, timing can become skewed (browser dependent).
Implementation
The voice announcements were obtained from the telephone time service that NIST provides. This laborious process involved recording and editing hundreds of calls. Calls were made with Google Hangouts, and all editing was done in Audacity. A small program was written to generate the tones and pulses according to the NIST specification. The voice samples and generated tones are then interleaved according to the current time and broadcast schedule of the selected station.
The application itself is entirely in Javascript. It leans heavily on the Howler and Driftless libraries to accurately sequence the audio clips.
