Are You Ready for the Next GPS Week Number Rollover?

Click here to read the Department of Homeland Security’s memorandum about the upcoming Global Positioning System Week Number Rollover Event.

Do your networks or systems use Coordinated Universal Time, or UTC? April 6, 2019, is probably a date worth marking in advance. Unlike a regular calendar event or holiday, this day will mark a special rollover of the GPS week number, or WN, that helps receivers tell time more precisely.  

The only question is whether your devices will react to the rollover event properly. Here's what you should know. 

Network Synchronization: Internet NTP Servers vs. GPS NTP Servers

Measuring time is about more than merely knowing when events occur. It's a vital prerequisite for synchronizing your operations, securing your data and serving your clientele. It pays to be precise, accurate and on-time, and your ability to do so depends on how good your time server is.

Unfortunately, you're unsure which kind of time server is best. You've narrowed it down to two choices: internet-based NTP and GPS-referenced Stratum 1 NTP. The distinctions aren't so clear, but these facts might make it easier to pick wisely.

Digital Clocks Keep Manufacturing Facilities in Sync

Synchronized time keeps your organization on-time, on-track and on-budget while helping to ensure compliance with ever-increasing traceability regulations. Even if your clocks are fairly accurate and only lose or gain a minute or two, those minutes can turn into hundreds of thousands of minutes of lost productivity when they affect each employee. A synchronized clock system ensures that your company can meet its time commitments, avoid unnecessary waste, meet transportation deadlines and streamline production. 

GPS Over Fiber Optic Timing Technology

In the world of timing systems, precision and accuracy are everything. In order to synchronize components across great distances, it’s vital that you retain the ability to communicate cleanly. 

Most typical coax-based GPS timing networks you encounter in the real world fall prey to basic signal propagation challenges. Latency, degradation, and interference are among some of your worst enemies, and your existing systems may not be able to overcome them. Could optical fiber systems hold the key to building superior timing architectures?

Daylight Saving Time Ending November 5th at 2AM

Daylight Saving Time  ends at 2:00AM on Sunday, November 5, 2017. Here are a few DST facts you may not know:

  1. Although you probably hear it referred to as daylight “savings”, the correct name is daylight “saving” time.
  2. Benjamin Franklin first suggested the idea of daylight saving time in his 1784 satirical essay, “An Economical Project for Diminishing the Cost of Light.”
  3. States that do not observe daylight saving time: Hawaii and Arizona (except for the state’s Navajo Nation).
  4. Since the Uniform Time Act of 1966, which established a standardized system of when daylight saving time started and ended throughout the United States, Congress has expanded the length of daylight saving time 3 times. Today, we observe it from March until November.
  5. Only about one-quarter of the world’s population, in approximately 70 countries, observe daylight saving time.

If you have a Masterclock Timing System in your facility, there is no need to worry - our systems configure to observe Daylight Saving Time in any time zone. All Masterclock analog clocks and digital displays easily configure to time zone and daylight saving time parameters. (The  software is included.) Check out our NTDS line of NTP digital displays and our TCDS series of time code driven digital clocks

GPS Threat Mitigation - Why Network Time Users Should Care

Whether you use GPS to maintain accurate UTC for your facility's IP-enabled security system or you simply employ it to keep your distributed scientific control and testing systems synced up, you can't afford to succumb to an unexpected threat. From hackers and unwitting smart device users to regional atmospheric conditions and once-in-a-lifetime solar weather patterns, the world can be a risky place for those who depend on network GPS timing.
