236 Part III — <strong>Data</strong> <strong>Hacking</strong> Turning Your PC into a High-Precision Atomic Clock For many people, having accurate time is important, and some people go to great lengths to ensure that the time on their PC is as accurate as possible. For the ultimate in accurate timing, you need access to an atomic clock. This will give you undisputed accuracy, but it comes with a huge price tag. Another option is to synchronize your PC clock with a time server on the Internet. Many of these use National Institute of Standards and Technology (NIST) time, but there are many others around the world. Here is a list of the U.S.-based NIST time servers: Name IP Address Location time-a.nist.gov 129.6.15.28 NIST, Gaithersburg, Maryland time-b.nist.gov 129.6.15.29 NIST, Gaithersburg, Maryland time-a.timefreq.bldrdoc.gov 132.163.4.101 NIST, Boulder, Colorado time-b.timefreq.bldrdoc.gov 132.163.4.102 NIST, Boulder, Colorado time-c.timefreq.bldrdoc.gov 132.163.4.103 NIST, Boulder, Colorado utcnist.colorado.edu 128.138.140.44 University of Colorado, Boulder time.nist.gov 192.43.244.18 NCAR, Boulder, Colorado time-nw.nist.gov 131.107.1.10 Microsoft, Redmond, Washington nist1.symmetricom.com 69.25.96.13 Symmetricom, San Jose, California nist1-dc.glassey.com 216.200.93.8 Abovenet, Virginia nist1-ny.glassey.com 216.200.93.9 Abovenet, New York City nist1-sj.glassey.com 207.126.98.204 Abovenet, San Jose, California nist1.aol-ca.truetime.com 207.200.81.113 TrueTime, AOL facility, Sunnyvale, California nist1.aol-va.truetime.com 64.236.96.53 TrueTime, AOL facility, Virginia These time servers offer you a way to quickly and regularly update your clock to ensure that it is as accurate as possible. Of course, it does require a connection to the Internet, and high traffic on the Internet or your connection can cause problems with the accuracy. If you are using time servers located on the Internet to adjust your PC clock, make sure that you are using the most accurate stratum 1 time servers. If you are interested in setting your clock over the Internet, rather than GPS, and you want control over the time server used, you can’t do much better than to use a piece of shareware called Sync-It with Atom, available from www.tolvanen.com/syncit.
