  • Computer Time Synchronization Computer Time Synchronization
    Computer Time Synchronization Computer Time Synchronization Michael Lombardi Time and Frequency Division National Institute of Standards and Technology The personal computer revolution that began in the 1970's created a huge new group of time and frequency users, those people who need to keep computer clocks on time. As you probably know, computer clocks aren't particularly good at keeping time. Simple clocks like your wristwatch and most of the clocks in your home usually keep better time than a computer clock. The poor performance of a computer clock can cause problems, since many computer applications require time kept to the nearest second or better. For example, the computers in a financial institution must keep very accurate records of when transactions were completed, for legal or other reasons. Computer systems that make physical measurements and acquire scientific data need to know precisely when the measurements were made. Software used on a manufacturing floor may need to turn a piece of equipment on or off at a specified time. Also, any system involved with synchronous communications must keep accurate time. For example, radio and TV stations may need computers that can switch feeds or link up with remotes at the right time. This paper describes several methods to keep accurate time by computer. Before looking at these methods, let's look at how a PC-compatible computer keeps time. Section 1.1 - How a Personal Computer keeps time Since the introduction of the IBM-AT personal computer in 1984, all PC-compatible computers have kept time the same way. Each PC contains two clocks, regardless of whether it uses the 286, 386, 486, or Pentium microprocessor (or a derivative).

  • SR500 GPS Master Clock
    SR500 GPS master clock The SR500 can be used on places where alternating current is available. The small GPS receiver is equipped with five meter cable. The offsets can be set easily with switches. The display is readable in the dark. GPS satellites all transmit the same time and date. The time is corresponding with UTC and GMT (Coordinated Universal Time and Greenwich Mean Time). The winter time in Great Britain is corresponding with this time. For having the same time with regard to light and dark the earth has been divided in 24 time sectors. For the local time and date each sector has its own offset in regarding to UTC/GMT. For example New York -5h, Central Australia +9½h and Rotterdam +1h. The offset is set by the rotating switch, indicating 0 up to F. Add or subtract with the set value via dipswitch nr. 1 of UTC: -/+. Half an hour+ can be added. For practical reasons sometimes the offset of the adjacent sector is copied. For Europe, the USA and Australia the DST (Daylight Saving Time) for the next fifty years has been programmed in tables which can be set with switches 1 and 2 of switch DST. The time to add during the summer time can be set on 0h (no DST), 0.5h, 1h and 1.5h. Features: Input voltage: 100 -240V, 50/60Hz. Housing: polycarbonate, dimensions 130x130x50mm, transparent cover. Clock line: available in 24VDC/400mA or 12VDC/400mA. Impulses: every minute or every 30 seconds, bipolar. Impulse length: 0.6 or 2 seconds.

  • Variability of Southern and Northern Periodicities of Saturn Kilometric
    VARIABILITY OF SOUTHERN AND NORTHERN SKR PERIODICITIES L. Lamy∗ Abstract Among the persistent questions raised by the existence of a rotational modu- lation of the Saturn Kilometric Radiation (SKR), the origin of the variability of the 10.8 hours SKR period at a 1% level over weeks to years remains intriguing. While its short-term fluctuations (20-30 days) have been related to the variations of the solar wind speed, its long-term fluctuations (months to years) were proposed to be triggered by Enceladus mass-loading and/or seasonal variations. This situation has become even more complicated since the recent identification of two separated periods at 10.8h and 10.6h, each varying with time, corresponding to SKR sources located in the southern (S) and the northern (N) hemispheres, respectively. Here, six years of Cassini continuous radio measurements are investigated, from 2004 (pre- equinox) to the end of 2010 (post-equinox). From S and N SKR, radio periods and phase systems are derived separately for each hemisphere and fluctuations of radio periods are investigated at time scales of years to a few months. Then, the S phase is used to demonstrate that the S SKR rotational modulation is consistent with an intrinsically rotating phenomenon, in contrast with the early Voyager picture. 1 Introduction The Saturn Kilometric Radiation (SKR) is an intense non-thermal radio emission pro- duced by auroral electrons moving along magnetic field lines, predominantly on the dawn arXiv:1102.3099v1 [astro-ph.EP] 15 Feb 2011 sector [Kaiser et al., 1980]. Its regular pulsation, whose origin still remains unexplained, was originally interpreted as a clock-like rotational modulation triggered by the planetary magnetic field, and thus directly relating to the planetary interior.

This device is a perfect alternative for synchronizing computer systems where no PCI slot or serial port is available for time synchronization. Key Features - USB 2.0 (Universal Serial Bus), 5V - Receiver status LEDs - Buffered hardware clock - Powered by USB (no extra power supply required) - Connector for external DCF77 antenna - Plastic Case - 3 Year Warranty rev 2017.0405.1416 Page 1/3 dcf600usb Description The DCF600USB shows the reception quality via its status LED and uses a buffered real time clock to maintain the time while powered off. There is no power supply required, it is powered by the Universal Serial Bus. The DCF600USB provides a professional solution to your time synchronization requirements in mobile applications like field data acquisition with a laptop/notebook and can be deployed whenever you need to synchronize a standalone PC, laptop or server when no PCI or serial port is available. The drivers package for Windows contains a time adjustment service which runs in the background and adjusts the Windows system time continously and smoothly. A monitor program is also included which lets the user check the status of the device and the time adjustment service, and can be used to modify configurable parameters.
