Jan-2022

One final example of adjusting clocks for local time zone offset is shown in Fig. 8-5

below. In this example, a third-party GPS clock is configured as PTP master, and

transmits its time reference in terms of TAI. PTP slave devices such as the CyTime

SER automatically adjust from TAI timescale to UTC timescale. Then, if desired, each

device adjusts its own clock for the local time zone according to its user setting.

Cyber Sciences recommends that event timestamps be based exclusively on UTC

or standard time, since discontinuities introduce potential for confusion and make

comparisons of historical values more difficult. For example, if events occur around

the time of the start of DST (“Spring forward”), their timestamps may appear one

hour further apart than the actual elapsed time.

Even worse, events recorded during the ending changeover (“Fall back”), can have

the same timestamps as events actually occurring one hour apart, with no way to

distinguish the truth. Clearly, the concept of Daylight Saving Time is not compatible

with timestamps in sequence of events recording.

To provide maximum flexibility, the CyTime SER supports adjustments for Daylight

Saving Time (DST) or Summer Time. However, it is recommended all event time-

stamps be stored in reference to UTC and adjusted for local time and DST by applica-

tion software at the point of consumption (edge software application) to enable

system wide display, analysis and analytics.
