[time-nuts] GPS Weekly Rollover Fail

[Steve Allen]

On Tue 2019-02-05T13:02:47-0800 Tom Van Baak hath writ:
> GPS time began Jan-1980 and the first rollover occurred in Aug-1999.
> The next one is April-2019 and Nov-2038 after that.

> We time nuts will be on full alert Saturday evening April 6 to
> Sunday morning April 7 to find and record any anomalies.

The actual GPS 1023 to 0 is not the only date when these events happen.
About a dozen buses in the county fleet are currently displaying dates
in mid 1999 presumably because their GPS firmware adds some constant
to the GPS week number.  Previous rollovers happened last year and
have been fixed; new rollovers happened around the beginning of this
year.
