No,  actually it is for my alarm clock.  Ignore the sawtooth?   Poppycock!   What self-respecting time nut could possibly tolerate being woken up with a +/- 15 ns uncertainty...

-----------------------
If this is for a computer and NTP then you may ignore the sawtooth.

GPS receiver sawtooth corrections are for people working at the
nanosecond level; important when you're working with disciplining
quartz or rubidium oscillators with stability at the 1e-12 level.

Computer timekeeping and NTP is a million times worse than this.
