> Hoping the one second delta is not me! I have seen consumer grade GPS receivers be off by a second while claiming to be OK. One case was a gross software bug. I think it was triggered by a pending leap second. http://www.megapathdsl.net/~hmurray/ntp/leap-gps.gif One was off by a second for 13 seconds just before the leap second kicked in. I assume they inserted it on GPS midnight rather than UTC midnight. The interesting cases are just off-by-a-second quirks. I think they happen when the receiver is recovering from a too-weak signal. http://www.megapathdsl.net/~hmurray/ntp/GPS18LVC-glitch1-off.gif http://www.megapathdsl.net/~hmurray/ntp/GPS18LVC-glitch2-off.gif -- These are my opinions, not necessarily my employer's.
