ISP Information:
A cluster of computers connected to a high-speed private network, running Linux, FreeBSD, or another free OS, and using Beowulf software to function like a single massively parallel computer. All nodes in the system are dedicated to running cluster jobs, and do not function as client machines. A Beowulf cluster is designed for high speed over-reliability. Typically there is only one node that is connected outside of the

AFAIK, CDMA phones pick up the time thenetwork operator sends, and TDMA and GSM phones don't have a timesource other than what the user sets manually.In any case, the clock in question (Verizon Boston, 617 637-xxxx) is"fast" right now by between 11 and 20 seconds, as compared to the USNaval Observatory Master Clock (UTC). The table below lists the timeas given by the Verizon clock right now, followed by the USNO time atthe Verizon beep, and the difference, which varies from beep to beep.I find it especially interesting that this clock will sometimescompletely skip the 20 second announcement.Verizon USNO Difference00 48 1210 59 1130 10 2040 22 1850 33 1700 45 1510 55 1520 03 1730 14 1640 26 1450 37 1300 48 1210 59 1130 11 1940 21 1950 33 17This is just ridiculous! The clock in DC at 202 844-xxxx is now slowby exactly 16 seconds. You can't even begin to explain that with leapseconds, since a clock which uses TAI or GPS time without the leapsecond correction would be fast, not slow.The uncorrected time should _never_ be presented to a user, and if itis, that's simply broken./john
