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.
