Nope. The resolution of the numbers is 1ns, the useful digits aka precision of the measurement doesn't extend that far down. That -30 would be equivalent to 931ps, which is completely implausible. I'll give you 30ns tops, that would be -25. You supposedly can get down to about half that, but it needs another atomic clock as a reference. http://www.allanstime.com/Publications/DWA/Science_Timekeeping/TheScienceOfTimekeeping.pdf https://ilrs.cddis.eosdis.nasa.gov/docs/timing/gpsrole.pdf The on-the-tin specification for GPS is 1µs, and that gives more or less exactly the -20 that the receiver reports, not so mysteriously after all.
