asciilifeform: sorta one of the places i was going with ntp.
asciilifeform: anybody's guess whether gps will decay from sat attrition (as glonas did in the 'roarin' 90s' ru) before usa implodes, civilian aviation on its territory Officially ends, and public freebie is turned off
asciilifeform: idea being that hitler can order the public band jammed, when he wants.
asciilifeform: other thing re: gps is that there is ~still~ an encrypted band (as of a few yrs ago, ~two~ separate ones)
asciilifeform: galileo was also in planning at the time (ru 'glonas' was in a serious state of decay and not relevant) and one legend goes that clinton's order was a failed gambit to sink it☟︎
asciilifeform: there was a whole industry, almost, devoted to this.
asciilifeform: one interesting aspect of the 'selective availability' era was that folks would actually collect the crud and broadcast... corrections! from an accurately-surveyed point
asciilifeform: 'give us root or we'll shoot' was the actual statement

asciilifeform: the traveling clocks against several atomic clocks left at home. Measurements confirmed that the clocks returned 22 nanoseconds ahead in time. ' << try sr at home!
asciilifeform: 'The talk concludes with a first-hand description of Project GREAT, perhaps the ultimate DIY clock experiment. Van Baak methodically selected three of his best portable cesium clocks, outfitted the family minivan (with his wife's permission) as a traveling time laboratory, and drove with his three children up the highest mountain in Washington State. After staying on Mt. Rainier for a long weekend they returned home to compare
asciilifeform: used to set the date and time. Not waterproof nor even water resistant. '
asciilifeform: 'The watch keeps time to a few nanoseconds per day. The attractive display is based on 7-segment red LED technology. Batteries are included (they last about 45 minutes but are rechargeable). AC adapter included. There are no adjustments for daylight saving time; however the clock does handle leap seconds and keeps track of the [Modified Julian] date. This HP wristwatch includes 5/10 MHz and 1 PPS outputs. An internal keypad is
asciilifeform: this is not seriously important in this case, but it follows 'unix philosophy' in the sense that a proggy returning false lets you use its failure as part of a shell script
asciilifeform: so you'd want to printf and then return false
asciilifeform: BingoBoingo: printf happens to return 1 (true) if it succeeded in printf-ing
asciilifeform: a few other nitpicks. the all-caps convention in bitcoind refers to constants
