For small differences NTP uses incremental adjustments. The clock
"ticks" a bit slower or faster until the kernel clock is in sync
with the time server. Applications do not notice this, unless they
compare with other time sources.
Keep in mind that this is about milliseconds since start, not about
country time or date.
