16 Applications often need to correlate the Zephyr internal time with external
17 time scales used in daily life, such as local time or Coordinated Universal
18 Time. These systems interpret time in different ways and may have
20 local time offsets like daylight saving time.
23 clocks underlying the cycle counter, the offset between time estimated from
24 the Zephyr clock and the actual time in a "real" civil time scale is not
