[time-nuts] Any (relatively) cheap TSIP GPS receivers without WNRO out there?

[Steven Sommars]

ntpsec, a fork of the classic NTP distribution, supports an option to
compensate for the 1024 week rollover:
https://docs.ntpsec.org/latest/ntp_conf.html

 time1 sec
Specifies a constant to be added to the time offset produced by the driver,
a fixed-point decimal number in seconds. Each "g" on the end of the
constant adds the number of seconds in a 10-bit GPS era; each "G" adds the
number of seconds in a 13-bit GPS era.
